摘要: A thermoplastic resin composition comprising (A) a propylene/ethylene block copolymer, (B) a combination of a low-crystalline ethylene/butene random copolymer resin and an amorphous ethylene/butene random copolymer rubber, or a combination of an ethylene/octene copolymer rubber and an ethylene/propylene copolymer rubber, (C) a specific block elastomer, and (D) talc. This composition has good injection molding properties, can reveal excellent flexural modulus, heat resistance and surface hardness, and is suitable for producing such injection-molded products as interior automotive trims.
