PURPOSE:To obtain a composition excellent in heat and impact resistance by adding a multilayered acrylic copolymer to an Nsubstituted maleimide/aromatic vinyl compound copolymer, aromatic vinyl compound/vinyl cyanide compound copolymer and ABS resin. CONSTITUTION:An N-substituted maleimide-containing thermoplastic resin composition obtained by blending (A) 100 pts.wt. resin composition consisting of (A1) 40-70wt.% heat-resistant resin consisting of 5-60wt.% random copolymer of an N-substituted maleimide and an aromatic vinyl compound and 40-95wt.% random copolymer of an aromatic vinyl compound, a vinyl cyanide compound and optionally other vinyl monomers and (A2) 30-60wt.% ABS based resin with (B) 5-20 pts.wt. acrylic polymer, having a multilayered structure, 20-50wt.% total amount of methyl methacrylate and styrene and 0.5-1.5 ratio thereof and containing 50-80wt.% rubber-like polymer. |
