PURPOSE:To provide a thermoplastic resin compsn. having good resistance to impact, heat and weather as well as excellent weld strength, by blending a specified rubbery polymer and an epoxy group-contg. polyolefin copolymer with a polycarbonate. CONSTITUTION:A rubbery polymer obtd. by polymerizing at least two compds. selected from an arom. vinyl compd. (e.g. styrene), a vinyl cyanide (e.g. acrylonitrile) and an alkyl unsaturated carboxylate (e.g. methyl acrylate) in the presence of a rubbery polymer (selected from among an acrylate ester polymer, chlorinated polyethylene and an ethylene/vinyl acetate copolymer) is used. 0.1- 40pts.wt. epoxy group-contg. olefin copolymer is blended with 100pts.wt. compsn. consisting of 90-10wt% polycarbonate and 10-90wt% said polymer.
