Abstract:
1. A thermoplastic resin composition comprising: 35 to 85% by weight of polypropylene resin (A), 1 to 35% by weight of elastomer (B), 2 to 30% by weight of inorganic filler (C), and 0.1 to 5% by weight of resin (D) defined below, wherein said amounts of the components (A), (B), (C) and (D) are each based on the combined weight of these four components: resin (D): resin comprising 60 to 80% by weight of a first segment which is a propylene homopolymer or a propylene-ethylene random copolymer and has an intrinsic viscosity, measured in tetralin at 135° C., of 5 dl/g or more and 20 to 40% by weight of a second segment which is a propylene homopolymer or a propylene-ethylene random copolymer and has an intrinsic viscosity, measured in tetralin at 135° C., of 0.8 to 1.2 dl/g, wherein the amounts of the first and second segments are each based on the combined weight of the two segments.
