PURPOSE:To obtain the titled composition composed of a polyamide resin, an epoxy group-containing copolymer and a rubber-reinforced resin, having excellent oil-resistance, chemical resistance, heat-deformation resistance, rigidity and impact strength and giving a molded article having excellent surface appearance. CONSTITUTION:The objective composition is composed of 20-80pts.wt. of a polyamide resin, (B) 20-80pts.wt. of an epoxy group-containing copolymer and (C) 0-50pts.wt. of a rubber-reinforced resin. The component B is preferably a copolymer composition comprising (i) 40-100pts.wt. of a copolymer produced by reacting 20-80wt% aromatic vinyl compound with 15-50wt% vinyl cyanide compound, 0.5-40wt% unsaturated epoxy compound and 0-30wt% other copolymerizable vinyl compound and (ii) 0-60pts.wt. of a graft copolymer produced by reacting the component (i) in the reaction of 5-95pts.wt. of a diene rubber with 95-5pts.wt. of a vinyl compound. |
