    摘要: A thermoplastic resin composition comprising a propylene polymer component, a styrene-containing elastomer component and talc. The propylene polymer component may be an ethylene-propylene block copolymer, polypropylene resin, a mixture of at least two propylene polymers each having different melt flow rate. The styrene-containing elastomer may be an elastomeric styrene-containing block copolymer represented by the following formula (I) or (II): ##STR1## wherein PS is a polystyrene block, PEB is a poly(ethylene-butene) block and m is an integer of 1 or more. Also, the styrene-containing elastomer may be a mixture of the elastomeric styrene-containing block copolymers having different melt flow rates.
