Abstract
A thermoplastic resin composition having excellent and well balanced physical properites such as chemical resistance, drop weight impact resistance and thermal stability which comprises (A) a styrenic polymer and (B) a ternary polymer comprising 50 to 98.5% by weight of an olefin, 0.5 to 10% by weight of an unsaturated dicarboxylic acid anhydride and 1 to 40% by weight of an unsaturated carboxylic acid alkyl ester, the weight proportion of the styrenic polymer (A) and the ternary polymer (B) being 100:0.5-200.
