PURPOSE: A thermoplastic resin composition is provided to have excellent shock resistance, heat resistance and scratch resistance by using vinyl cyanide-alkylmethacrylate-maleic anhydride random copolymer. CONSTITUTION: A thermoplastic resin composition comprise 20-50 parts by weight of acrylonitrile-butadiene-styrene copolymer, 20-70 parts by weight of aromatic vinyl-vinyl cyanogens-alkylmethacrylate-maleic anhydride random copolymer consisting of an aromatic vinyl compound in chemical formula 1, a vinyl cyanide in chemical formula 2, an alkyl methacrylate compound in chemical formula 3, and a maleic anhydride compound in chemical formula 4, and 5-50 parts by weight of styrene-acrylonitrile copolymer. |
