Title of Invention

BUTENE-1 (CO) POLYMERS AND PROCESS FOR THEIR PREPARATION

Abstract

Butene-l homopolymers, or copolymers containing up to 20% by weight of alpha oletlus having from 2 to 10 carbo11 atoms other than butene-l, characterized by the following properties: ' (i) a Molecular Weight Distribution (MWD) in terms of Mw/Mn, measured by GPC analysis according to the method specified above, of lower than 6; and (ii) a melt strength (measured according to the method specified above) higher than 2.8.

resulted to be 2.5 g. The mechanical properties shown by the polymers disclosed in said While there is no particular limitation as to the molecular weight of the polymers, it is washings with hydrocarbon solvents until chloride ions disappeared. According to a further I more times. Moreover, are also preferred the silicon compounds in which a is 0, c is 3, R6 is a branched prepolymerization with monomer amounts and polymerization times necessary to obtain s of molten polymer operating at a specific stretch velocity, in particular, the Dolvmer to be 200 ml of fresh TiCL were added, the mixture was reacted at 120 C for one hour then the following characteristics: Isotactic Index (%nimiran) 99% The butene-1 homo or copolymers according to claim 12 containing from 1 to Process according to claim 17 carried out in liquid monomer.
