PAINTABLE POLYOLEFIN COMPOSITIONS

摘要

A paintable polyolefin composition comprising: A) 70-99 parts by weight of an olefin polymer selected from the group consisting of homopolymers of ethylene, propylene, butene-l or 4-methyl-pentene-1, and crystalline or amorphous copolymers of said olefins with one or more different CH2=CHR olefins, where R is hydrogen or an alkyl radical with 1-10 carbon atoms, and mixtures thereof B) 1-30 parts by weight of an X-Y block copolymer, where X is a polydiene, optionally partially or totally hydrogenated, and Y is a CH2=CR-COOR' acrylic or methacrylic acid ester polymer or copolymer, where R is hydrogen or methyl and R' is a linear or branched C1-18 alkyl, C3-18 cycloalkyl or C6-18 aryl radical, the number average molecular weight of said copolymer being from 1,000 to 200,000 g/mole, and the content of acrylic or methacrylic ester polymer or copolymer being from 1 to 70% by weight.
