Abstract

A thermoplastic resin composition consisting essentially of: PA0 (A) 20 to 80% by weight of a polycarbonate having a viscosity-average molecular weight of 14,000 to 27,000, PA0 (B) 10 to 70% by weight of a maleimide resin obtained by polymerizing 95 to 35 parts by weight of a monomer mixture consisting of 10 to 70% by weight of a maleimide compound, 25 to 80% by weight of an aromatic alkenyl compound, 5 to 40% by weight of an alkenyl cyanide compound and optionally 50% by weight or less of a monomer copolymerizable therewith, in the presence of 5 to 65 parts by weight of at least one rubber-like polymer selected from the group consisting of an ethylene-propylene-nonconjugated diene rubber, an ethylene-propylene rubber and an acrylic rubber, and PA0 (C) 5 to 70% by weight of a styrene resin obtained by polymerizing 95 to 20 parts by weight of a monomer mixture consisting of 5 to 40% by weight of an alkenyl cyanide compound, 10 to 95% by weight of an aromatic alkenyl compound and optionally 0 to 70% by weight of at least one other alkenyl monomer copolymerizable with said compounds, in the presence of 5 to 80 parts by weight of a rubbery polymer. Said resin composition is excellent i…
