Full Text 1. Field of the Invention
The present invention relates to a propylene based resin composition and the use thereof.
More particularly, the invention (a first aspect of the invention) relates to a thermoplastic resin composition
comprising a specific propylene/α-olefin copolymer, to a cross linked product of the thermoplastic resin composition and to a molded article comprising the thermoplastic resin composition and the cross linked product. Even more particularly, the invention relates to a thermoplastic resin composition capable of molding at low temperatures as well as obtaining a molded article having an excellent balance between flexibility and scratch resistance/whitening resistance, a cross linked product of the thermoplastic resin composition, and to a molded article formed from the thermoplastic resin composition and the cross linked product.
Further, more particularly, the invention (a second aspect of the invention) relates to a propylene based resin composition and a molded article obtained from the propylene

Based resin composition. Even more particularly, the invention relates to a propylene based resin composition containing a high proportion of inorganic filler and having excellent flexibility, mechanical strength, elongation at breakage, heat resistance, scratch resistance, whitening resistance and flame retardance, and a molded article using the propylene based resin composition. 2. Description of the Related Art
Various resin compositions have been developed to use in various applications. As described below, a propylene based resin composition may be used depending upon the application. However, characteristics required for the respective applications are desired to be further improved.
For example, various materials in the past have been used for components, parts and sheets requiring rubber elasticity, which are used for automobile parts, industrial machinery parts, electric/electronic parts, building materials cap liners. A vinyl chloride resin has been the most commonly used resin in these applications in the past.
However, the vinyl chloride resin has inferior rubber elasticity as compared with vulcanized rubber, and therefore, the uses thereof are limited. Further, in recent years, for reasons such as difficulties in incineration of the vinyl

Chloride resin, the development of an alternative material is desired.
On the one hand, a thermoplastic elastomer is known as a polymeric material which can be plasticized at high temperatures and molded in the same way as a plastic and has rubber elasticity at room temperature. Examples of a recyclable olefin thermoplastic elastomer include a composition of polypropylene and a styrene elastomer (Patent Document 1). This material has good strength, flexibility and heat resistance, and therefore can be well used for cap
Liners or the like.
On the other hand, because further improvement in
Flexibility can be attained, an olefin thermoplastic
Elastomer comprising polypropylene and an ethylene/a-olefin copolymer is used (Patent Document 2).
However, there was a problem in that the above-mentioned olefin thermoplastic elastomer had insufficient balance between flexibility and scratch resistance, and scratch resistance and whitening resistance were lowered when flexibility was attained. These are technical backgrounds of the first aspect of the invention.
Furthermore, a polypropylene resin is a material having heat resistance, mechanical strength and scratch resistance better than a polyethylene resin (polyethylene elastomer)

And thus, the molded article thereof is used in wide applications. A general molded article obtained from polypropylene and inorganic filler also has excellent heat resistance and mechanical strength, while the article is poor in flexibility and impact resistance. Therefore, a polyethylene resin has been mainly used in applications requiring characteristics such as flexibility and impact resistance. However, there was a problem in that the molded article obtained from the polyethylene resin was poor in scratch resistance.
On the other hand, as the molded article comprising a polypropylene resin and inorganic filler (flame retardant), an electric wire or wire harness requiring scratch resistance is known. In addition, Patent Document 3 discloses an insulated wire for automobiles, using a specific propylene polymer. However, the molded article used in Patent Document 3 was excellent in flexibility and impact resistance, but was insufficient in scratch resistance. These are technical backgrounds of the second aspect of the invention.

For example, in the case that the composition contains isotactic polypropylene (A2) as an essential ingredient, when the composition is used in applications such as convenience goods, skin materials (synthetic leathers), cap liners, automobile interior materials, packings, gaskets, waterproof sheets or the like, as described later, the component (B2) may be contained in an amount of 5 to 50% by weight, preferably 15 to 50% by weight, more preferably 20 to 45% by weight, the component (C2) may be contained in an amount of 5 to 90% by weight, preferably 10 to 80% by weight, more preferably 20 to 75% by weight, the component (A2) may be contained in an amount of 5 to 45% by weight, preferably 5 to 40% by weight, more preferably 5 to 35% by weight, and the component (D2) may be contained in an amount of 0 to 50% by weight, preferably 0 to 40% by weight, more preferably 0 to 30% by weight. Additionally, in this case, the composition may contain a softening agent (E2) as an optional ingredient. When the composition contains the component (E2) , the content of the component (E2) is 1 to 400 parts by weight, preferably 1 to 350 parts by weight,

more preferably 1 to 300 parts by weight, based on 100 parts by weight of the total amount of the components (A2), (B2), (C2) and (D2) . In this case, the composition has an excellent balance among, in particular, flexibility, scratch resistance and whitening resistance. Further, the composition also has excellent low-temperature kneadability.
Furthermore, for example, in the case that the composition contains isotactic polypropylene (A2) as an essential ingredient, when the composition is used in applications such as home electric appliance parts, automobile exterior materials, sheets for packaging, monofilament or the like, as described later, the component (B2) may be contained in an amount of 5 to 45% by weight, preferably 5 to 35% by weight, more preferably 5 to 30% by weight, the component (C2) may be contained in an amount of 5 to 45% by weight, preferably 5 to 35% by weight, more preferably 5 to 30% by weight, the component (A2) may be contained in an amount of 50 to 90% by weight, preferably 60 to 90% by weight, more preferably 65 to 90% by weight, and the component (D2) may be contained in an amount of 0 to 30% by weight, preferably 0 to 25% by weight, more preferably 0 to 20% by weight. Additionally, in this case, the composition may contain a softening agent (E2) as an optional ingredient. When the composition contains the

component (E2), the content of the component (E2) is 1 to 100 parts by weight, preferably 1 to 70 parts by weight, more preferably 1 to 50 parts by weight, based on 100 parts by weight of the total amount of the components (A2), (B2), (C2) and (D2). In this case, the composition particularly has an excellent balance among mechanical properties such as tensile elasticity, transparency, impact resistance and whitening resistance.
Furthermore, other resins, other rubbers, inorganic fillers or the like can be blended to the thermoplastic resin composition (X2) within the range that does not impair the object of the first embodiment of the invention. Moreover, it can be blended with additives such as a weathering stabilizer, a heat stabilizer, an antistatic agent, an antislip agent, an antiblocking agent, an antifogging agent, a lubricant, a pigment, a dye, a plasticizer, an antiaging agent, a hydrochloric acid absorbent, an antioxidant, and a nucleating agent. The amount of the other resins, other rubbers, inorganic fillers, additives or the like added is not particularly limited as long as the amount is within the range that does not impair the object of the first embodiment of the invention, but there can be exemplified an embodiment that the total amount of a propylene/a-olefin copolymer (B2), a styrene-based

elastomer (C2), isotactic polypropylene (A2) used if
necessary, an ethylene/a-olefin copolymer (D2) used if necessary, and a softening agent (E2) used if necessary, is, for example, 60 to 100% by weight, preferably 80 to 100% by weight of the total composition. The other components comprise the other resins, rubbers, additives, inorganic fillers or the like as described above.
The thermoplastic resin composition (X2) can be obtained using a known kneading machine such as a single-screw or twin-screw extruder, a Banbury mixer, a roll or a calendar, and is preferably obtained using a molding machine such as a single-screw or twin-screw extruder, capable of continuously extruding and kneading.
Further, the thermoplastic resin composition (X2) can also be crosslinked, if necessary. The crosslinked product of the invention can be produced by dynamic crosslinking the thermoplastic resin composition in the presence of a known crosslinking agent, crosslinking aid or the like, or alternately molding the thermoplastic resin composition (X2) alone or kneading the thermoplastic resin composition (X2) with a crosslinking agent, crosslinking aid or the like and molding them, heating or irradiating them with an electron beam, etc., and then crosslinking them.
In particular in the dynamic crosslinking, it is

preferred in that the propylene/a-olefin copolymer (B2) can be molded at low temperature since it is a low melting point material and crosslinking conditions in dynamic crosslinking the thermoplastic resin composition (X2) are in a broad range.

The thermoplastic resin composition (X2) and the crosslinked product thereof can be molded into a molded article of various shapes, e.g., sheet, unstretched film or stretched film, and filament. Further, the molded article formed from the thermoplastic resin composition (X2) or comprising crosslinked product thereof may be composed of completely the thermoplastic resin composition (X2) or the crosslinked product thereof according to the invention or at least partially the thermoplastic resin composition (X2) or the crosslinked product thereof. For example, like a laminated film, the molded articles may be a composite with other thermoplastic resin compositions having a different resin formulation, or a composite with other materials, of which a part comprise the thermoplastic resin composition (X2) or the crosslinked product thereof according to the invention.
Specific examples of the molding method include a known

thermoforming method such as extrusion molding, injection molding, inflation molding, blow molding, extrusion blow molding, injection blow molding, press molding, vacuum molding, calendar molding and foam molding. The molded article will be explained hereinafter by several examples.
When the molded article is, for example, an extrusion-molded article, it is not particularly limited in shape and type, but examples thereof include sheet, film (unstretched), pipe, hose, wire coating and tube. In particular, sheet (surface material), film, tube, catheter, monofilament and nonwoven fabric and the like are preferable.
The thermoplastic resin composition (X2) or the crosslinked product thereof can be extrusion-molded by a conventionally known extruder under conventionally known molding conditions. For example, the molten thermoplastic resin composition (X2) can be extruded by a single-screw, kneading, ram or gear extruder through a specific die or the like into a desired shape.
The above extruded sheet or extruded film (unstretched) can be stretched by a known stretching process, e.g., tender (longitudinal/transverse or transverse/longitudinal stretching), simultaneous biaxial stretching or monorail stretching to obtain a stretched film.
The sheet or unstretched film is stretched at a

stretching ratio usually in the range of about 20 to 70 folds in the case of biaxial stretching, and about 2 to 10 folds in the case of monoaxial stretching. The thickness of the stretched film obtained by stretching is preferably
about 5 to 200 jam.
Further, an inflation film can also be produced as a film-shaped molded article. Inflation molding makes draw down of moldings difficult.
The sheet or film molded article made of the thermoplastic resin composition (X2) or the crosslinked product thereof has excellent flexibility, strength, heat resistance, stretch property, impact resistance, aging resistance, transparency, through-view property, gloss, rigidity, moisture-proofness and gas barrier property. Thus, it can be widely used for a packing film or the like.
Furthermore, the filament molded article can be produced by, e.g., extruding the molten thermoplastic resin composition (X2) or the crosslinked product thereof through a spinneret. Specifically, a spunbonding or melt blown process is suitably used. The filament thus produced may be further stretched, to an extent of molecular orientation at least in one axial direction of the filament, preferably at a stretching ratio usually in the range of about 5 to 10 folds. The filament made of the thermoplastic resin

composition (X2) or the crosslinked product thereof has excellent transparency, flexibility, strength, heat resistance, impact resistance, and stretch property.
The thermoplastic resin composition (X2) or the crosslinked product thereof can also be injection-molded into various shapes as an injection-molded article by a conventionally known injection molding equipment under known conditions to produce an injection-molded article. The injection-molded article made of the thermoplastic resin composition (X2) or the crosslinked product thereof has excellent flexibility, transparency, strength, heat resistance, impact resistance, surface gloss, chemical resistance, abrasion resistance and the like. Thus, it can be widely used for, e.g., trim materials for automobile interiors, automobile exterior materials, home electric appliance housings, containers and the like.
The thermoplastic resin composition (X2) or the crosslinked product thereof can also be blow-molded by a conventionally known blow molding equipment under known conditions to produce a blow-molded article. In this case, the blow-molded article made of the thermoplastic resin composition (X2) or the crosslinked product thereof may be a multilayered molded article and the article may comprise at least one layer of the thermoplastic resin composition (X2).

Taking extrusion-blow molding as an example, the thermoplastic resin composition (X2) or the crosslinked product thereof, molten at a resin temperature of 100 to 300°C, is extruded through a die into a tubular parison, which is blown with air while being held in a mold of desired shape, and then put in a mold while being kept at a resin temperature of 130 to 300°C, to form the blow molding. It is stretched (blown) preferably at a ratio of about 1.5 to 5 folds in the transverse direction.
When injection-blow molding is used, the thermoplastic resin composition (X2) or the crosslinked product thereof, molten at a resin temperature of 100 to 300°C, is injected into a parison mold to form the parison, which is blown with air while being held in a mold of desired shape, and then put in a mold while being kept at a resin temperature of 120 to 300°C, to form the hollow article. It is stretched (blown) preferably at a ratio of 1.1 to 1.8 folds in the longitudinal direction and 1.3 to 2.5 folds in the transverse direction.
The blow-molded article made of the thermoplastic resin composition (X2) or the crosslinked product thereof is excellent in transparency, flexibility, heat resistance and impact resistance, and further excellent in moisture-proofness.

The press-molded article may be exemplified by the mold-stamped article. For example, when the base and surface materials are simultaneously pressed to form the composite, monolithic molded article by mold stamping, the thermoplastic resin composition (X2) or the crosslinked product thereof according to the first embodiment of the invention can be used for the base.
The specific examples of the mold-stamped articles include automobile interior materials, e.g., door trim, rear package trim, seat back garnish and instrument panel.
The press-molded article made of the thermoplastic resin composition (X2) or the crosslinked product thereof has excellent flexibility, heat resistance, transparency, impact resistance, aging resistance, surface gloss, chemical resistance, abrasion resistance and the like.
The molded article made of the thermoplastic resin composition (X2) or the crosslinked product thereof is excellent in mechanical properties such as hardness or the like, rubber elasticity and permanent compression set at room temperature as well as rubber elasticity and compression set at high temperature, and further excellent in transparency and scratch resistance. When a softening agent (E2) is contained, the article is excellent in balance between appearance-maintaining property and rubber

Elasticity/compression set, particularly even at high temperature. Further, the article is easy to recycle and is further obtained at low cost. Therefore, the thermoplastic resin composition (X2) or the crosslinked product thereof is suitably used for automobile interior parts, automobile exterior parts, home electric appliance parts, civil engineering or building material parts, sheets for packaging, cap liners, gaskets and convenience goods, and is suitably used for automobile interior parts or automobile exterior parts where rubber elasticity is required, particularly even at high temperature.

Furthermore, examples of the propylene-based polymer (A6) include homopolypropylene having excellent heat resistance (a known one having usually 3 mol% or less of copolymerizing components other than propylene), block polypropylene having an excellent balance between heat resistance and impact resistance (a known one having usually 3 to 30% by weight of a rubber component eluted in n-decane) , and random polypropylene having an excellent balance between flexibility and transparency (a known one having a melting peak, as measured by a differential scanning calorimeter (DSC), usually in the range of 120°C or more, preferably in the range of 125 to 150°C), and these can be selected or


Used together with each other in order to obtain desired properties.
Such propylene-based polymer (A6) can be prepared, for example, by polymerization of propylene or copolymerization
Of propylene and the other oc-olefin in the presence of a Ziegler catalyst system comprising a solid catalyst component essentially containing magnesium, titanium and halogen, an organoaluminum compound and an electron donor, or a metallocene catalyst system comprising a metallocene compound as one component of the catalyst.

Examples of the propylene-based polymer (B6) used in the second embodiment of the invention include a propylene homopolymer, and a copolymer of propylene and at least one a-olefin having 2 to 20 carbon atoms other than propylene. Herein, examples of the a-olefin having 2 to 20 carbon atoms other than propylene include the same as those exemplified in the propylene-based polymer (A6) and the preferable ranges thereof are also the same as those for the propylene polymer.
These oc-olefins may form a random or block copolymer with propylene.
The propylene-based polymer (B6) contains usually 40 to 100 mol%, preferably 40 to 99 mol%, more preferably 40 to 92

mol%, even more preferably 50 to 90 mol% of a unit derived from propylene and usually 0 to 60 mol%, preferably 1 to 60 mol%, more preferably 8 to 60 mol%, even more preferably 10 to 50 mol% of a unit derived from an a-olefin having 2 to 20 carbon atoms (provided that propylene is excluded), which is used as a comonomer (Here, the total amount of propylene and the a-olefin having 2 to 20 carbon atoms is 100 mol%.).
The propylene-based polymer (B6) has a melt flow rate (MFR, ASTM D1238, 230°C, under a load of 2.16 kg) usually in the range of 0.1 to 50 (g/10 min).
Further, the propylene-based polymer (B6) has a melting point, as measured by differential scanning calorimetry analysis (DSC), of less than 120°C, or a melting point, as measured by DSC, is not observed in the propylene-based polymer (B6) . Preferably, the propylene-based polymer (B6) has a melting point of 100°C or less, or a melting point which is not observed in the propylene-based polymer (B6). The term " the melting point is not observed" as referred to herein means that a melting endothermic peak of crystal having a melting endothermic enthalpy of crystal of 1 J/g or more is not observed in the range of -150 to 200°C. Conditions of measurement are as described in Examples according to the second embodiment of the invention.

The propylene-based polymer (B6) has an intrinsic

If the mm fraction is in the above-mentioned range, it is excellent particularly in balance between flexibility and mechanical strength and thus it is suitable for the second embodiment of the invention. The mm fraction can be measured using the method described in page 21, line 7 to page 26, line 6 of the international publication of WO 2004-087775.
A method for producing the propylene-based polymer (B6) is not particularly limited, but the propylene polymer can be produced by polymerization of propylene or
copolymerization of propylene and the other a-olefin in the presence of a known catalyst that an olefin can be polymerized stereospecifically in an isotactic or syndiotactic structure, for example, a catalyst mainly containing a solid titanium component and an organometallic

By using the random copolymer (B6-1) of propylene and
An a-olefin having 4 to 20 carbon atoms, the compatibility thereof with a crystalline polypropylene component is expressed, and thus the propylene based resin composition having further excellent mechanical strength, elongation at breakage, scratch resistance and whitening resistance, is obtained.
Furthermore, the random copolymer (B6-2) of propylene,

ethylene and an oc-olefin having 4 to 20 carbon atoms also has the compatibility thereof with a crystalline polypropylene component, similarly the random copolymer (B6-
1) of propylene and an a-olefin having 4 to 20 carbon atoms, and thus the propylene based resin composition having further excellent flexibility, scratch resistance and whitening resistance, is obtained by using the random
copolymer (B6-2) of propylene, ethylene and an a-olefin having 4 to 20 carbon atoms.
Hereinafter, the random copolymer (B6-1) of propylene and an a-olefin having 4 to 20 carbon atoms and the random copolymer (B6-2) of propylene, ethylene and an a-olefin having 4 to 20 carbon atoms suitably used in the second embodiment of the invention will be explained in detail.
[Random copolymer (B6-1) of propylene and a-olefin having 4 to 20 carbon atoms]

The melting point Tm of the random copolymer (B6-1) of

The melting point Tm is usually less than 120°C, preferably 100°C or less, more preferably in the range of 40 to 95°C, and even more preferably in the range of 50 to 90°C. When the melting point Tm is in the above range, a molded article, which is excellent particularly in balance between flexibility and strength, is obtained. Moreover, it is advantageous in that the molded article formed from the composition of the second embodiment of the invention is easy to manufacture because the surface stickiness of the molded article is reduced.
