PURPOSE:To obtain the title composition which can give a molding having excellent low-temperature impact resistance by mixing a resin mixture comprising a polyamide resin and a specified rubber-reinforced styrene graft copolymer with an N-substituted maleimide/unsaturated dicarboxylic acid anhydride copolymer. CONSTITUTION:100 pts.wt. resin mixture comprising 20-80wt.% polyamide resin (desirably, nylon 6 or nylon 66) and 20-80wt.% rubber-reinforced styrene graft copolymer (wherein 40-60 pts.wt. monomer component comprises 60-80wt.% aromatic vinyl monomer and 20-40wt.% vinyl cyanide monomer, a mean particle diameter of grafted rubber particle is 0.2-1.0mum, a degree of grafting is 40-80% and a specific viscosity of the resin component is 0.05-0.10) is mixed with 0.01-40 pts.wt. copolymer comprising 50-80wt.% aromatic vinyl monomer, 5-47wt.% N-substituted maleimide monomer, 0.01-30wt.% alpha,beta-unsaturated dicarboxylic acid anhydride monomer and 0-30wt.% vinyl cyanide monomer and, optionally, 0-15 pts.wt. SNM resin to obtain an impact-resistant thermoplastic resin composition. |
