PURPOSE:To obtain a thermoplastic resin composition having excellent chemical resistance by compounding a rubber-reinforced styrene resin with an olefin copolymer containing epoxy group and a specific terpolymer. CONSTITUTION:The objective composition can be produced by compounding (A) 100 pts.wt. of a rubber-reinforced styrene resin with (B) 0.1-40 pts.wt. (preferably 0.5-20 pts.wt.) of an olefin copolymer containing epoxy group and composed of an unsaturated epoxy compound, an olefin and, as necessary, an ethylenic unsaturated compound, preferably an ethylene-glycidyl methacrylate copolymer, ethylene-methyl methacrylate-glycidyl methacrylate copolymer, etc., and (C) 0.1-40 pts.wt. (preferably 0.5-20 pts.wt.) of an unsaturated dicarboxylic acid anhydride/olefin/unsaturated carboxylic acid alkyl ester terpolymer, preferably maleic anhydride/ethylene/butyl acrylate terpolymer, etc. |
