Title of Invention | SILYL (METH) ACRYLATE COPOLYMERS, PROCESSES FOR PREPARING THE SAME, |
---|---|
Abstract | Disclosed is a silyl (meth) acrylate copolymer which comprises 20 to 80% by weight of (a) silyl (meth) acrylate constituent units represented by the following formula (I), 0.01 to 40% by weight of (b) acrylic unsaturated monomer constituent units represented by the following formula (II) and 5 to 79.99% by weight of (c) unsaturated monomer constituent units other than the constituent units (a) and (b), with the proviso that the total amount of the constituent units (a), (b) and (c) is 100% by weight, and which has a weight-average molecular weight, as measured by GPC, of not more than 200,000. wherein R¹ is a hydrogen atom or a methyl group, and R², R³ and R4 may be the same or different and are each an alkyl group, a cycloalkyl group or a phenyl group which may have a substituent group.wherein R5 a hydrogen atom or a methyl group, Z is an oxygen atom or -NR7, when Z is an oxygen atom, R6 is a hydroxyalkyl or hydroxycloalkyl group which may have a substituent group or a polyalkylene glycol group represented by the formula-(R8O)nH (wherein R8 is an alkylene group and n is an integer of 2 to 50), and when Z is -NR7, R7 is an alkyl group which may be substituted with any of a halogen, a hydroxyl group, an amino group, a substituted amino group, an acyl group and an alkoxy group, and R6 is a hydrogen atom. Also disclosed are a process for preparing the silyl(meth)acrylate copolymer, an antifouling paint composition comprising the copolymer, a coating film formed the paint composition, a hull with the coating film, and an antifouling method using the paint composition. By the use of the silyl(meth)acrylate copolymer, there can be produced an antifouling paint capable of forming an antifouling coating film which hardly suffers from occurrence of cracks, has excellent adhesive strength and therby hardly suffers from peeling, can be favorably controlled in the hydrolysis rate, and is excellent in antifouling performance (antifouling activities) and long-term antifouling properties. |
