PURPOSE:To provide a thermoplastic resin composition excellent in not only impact resistance, rigidity, heat distortion resistance, and moldability but also mattedness, by adding a specified amount of a silylated vinyl copolymer to an epoxy-containing ABS resin. CONSTITUTION:0.5-30 pts.wt. silylated vinyl copolymer is added to 100 pts.wt. epoxy-containing ABS resin to produce a thermoplastic resin composition having excellent mattedness. An example of the ABS resin is a copolymer composition comprising a graft copolymer formed by grafting glycidyl methacrylate, acrylonitrile and styrene onto polybutadiene. An example of the vinyl copolymer is a styrene/methylmethacrylate/gamma-methacryloxypropyltrimethoxysilane copolymer. The obtained composition is suitable for automobile interior furnishings. |
