PURPOSE:To obtain a thermoplastic resin composition of excellent impact resistance, moldability and chemical resistance, by using a crystalline polyolefin, a polycarbonate and a specific graft copolymer. CONSTITUTION:100pts.wt. of (A) 95-5wt.%, preferably 90-10wt.% of a crystalline polyolefin, preferably polypropylene, and (B) 5-95wt.%, preferably 10-90wt.% of a polycarbonate of 10,000-100,000, preferably 20,000-50,000 weight average mol.wt., are combined with (C) 5-100pts.wt., preferably 10-50 pts.wt. of a graft copolymer which is produced by grafting styrene monomer and acrylic monomer onto an ethylene-propylene-diene terpolymer or an ethylene-propylene copolymer in which the content of the styrene monomer is 95-50wt.%, while the acrylonitrile monomer is 5-50wt.%. |
