PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition excellent in heat resistance, mechanical strength, water resistance, etc., by containing a polyamide resin, polypropylene resin, modified polyolefin resin and specific two kinds of polycarbonate resins. SOLUTION: This composition comprises (A) 10-90 wt.% of polyamide resin preferably, nylon 6, nylon 66, etc., (B)10-90 wt.% of polypropylene resin having crystallinity comprising propylene copolymer containing at least 50% of propylene or propylene homopolymer, (C) 5-45 wt.% of modified polyolefin resin for example, a graft polymer obtained by graft polymerizing unsaturated carboxylic acid(derivatives) onto a polyolefin, (D) 4-25 wt.% of an aromatic- polycarbonate resin obtained by graft polymerizing an aromatic vinyl monomer and vinyl cyanide on the polycarbonate resin, (E)4-25 wt.% of polycarbonate resin preferably, having an average molecular weight of 1000-20×10<4> , and (F) an antioxidant, etc., if required. |
