<p>PURPOSE:To provide the titled compsn. having excellent platability, heat resistance and transparency and useful as a material in the fields of automobile, household appliance, precision equipment, etc., by blending a thermoplastic resin consisting of an imide copolymer and a specified copolymer with a polycarbonate resin. CONSTITUTION:An arom. vinyl monomer (a), an unsaturated dicarboxylic acid imide derivative (b) (e.g. N-phenylmaleimide) and a copolymerizable vinyl monomer (c) (e.g. acrylonitrile), etc. are copolymerized in a solvent at 80-350 deg.C to obtain an imide copolymer (A) composed of 30-90% (by weight; the same applies herein below) residue of component (a), 3-7% residue of component (b) and 0-40% residue of component (c). 5-95% thermoplastic resin consisting of 10-90pts.wt. component A and 90-10pts.wt. rubbery copolymer having a number-average particle size of 200mmu or below, obtd. by grafting 30-80% arom. vinyl monomer, 0-40% vinyl cyanide monomer and 0-40% other copolymerizable monomer onto 3-7% rubbery polymer (e.g. polybutadiene) is blended with 95-5% polycarbonate resin.</p> |
