Abstract
A thermoplastic resin composition having excellent impact strength and high heat distortion temperatures consisting essentially of (A) 10 to 90 parts by weight of a styrene-methacrylic acid type copolymer resin selected from a styrene/methacrylic acid copolymer resin obtained by polymerizing 97 to 65% by weight of styrene and 3 to 35% by weight of methacrylic acid and a styrene/methyl methacrylate/methacrylic acid copolymer resin obtained by polymerizing 48.6 to 64.9% by weight of styrene, 48.4 to 0.1% by weight of methyl methacrylate and 3 to 35% by weight of methacrylic acid, (B) 90 to 10 parts by weight of a graft copolymer resin obtained by polymerizing 70 to 20% by weight of methyl methacrylate or a monomeric mixture composed of from less than 100 to 20% by weight of methyl methacrylate and from more than 0 to 80% by weight of styrene in the presence of 30 to 80% by weight of a rubbery polymer, and (C) 0.001 to 0.2% by weight as silicon, based on the total weight of (A) and (B), of an organopolysiloxane.
