(57) [Summary] [Structure] 50 to 10 parts of crystalline polyolefin and aromatic vinyl per 100 parts by weight of rubber-reinforced styrene resin (A). Polyolefin graft polymer (B) obtained by polymerizing a monomer consisting of 0% by weight, vinyl cyanide and / or 0 to 50% by weight of unsaturated carboxylic acid alkyl ester, and olefin, unsaturated carboxylic acid anhydride and unsaturated carboxylic acid 0.1-40 parts by weight in total of the terpolymer (C) consisting of alkyl ester, and (B) / The thermoplastic resin composition in which the ratio of (C) is 5/95 to 95/5 (weight ratio). [Effect] It has excellent chemical resistance and impact strength after coating, and can be suitably used especially for automobile exterior materials. |
