Japanese Patent JPH0323562
Kind Code:
B2
Abstract:
PURPOSE:To obtain the title composition excellent in impact resistance, interfacial peeling resistance, coating property and moldability, by mixing a thermoplastic polymer selected from among a (modified) polycarbonate polymer, a (modified) polysulfone polymer and a nitrile polymer with a specified modified block copolymer. CONSTITUTION:100pts.wt. at least one thermoplastic polymer (A) selected from among (a) a polycarbonate polymer or a modified product obtained by blending this polymer with a styrene polymer, (b) a polysulfone polymer or a modified product formed by blending this polymer with a styrene polymer and (c) a nitrile polymer such as polyacrylonitrile is mixed with 1-100pts.wt. modified block copolymer (B) obtained by adding an unsaturated dicarboxylic acid (derivative) (e) such as maleic acid (anhydride) to a block copolymer (d) of an average MW of 10,000-1,000,000, formed by block-copolymerizing a vinylaromatic compound with a conjugated diene compound at a weight ratio of 70/30-95/5.
