PURPOSE:To obtain a thermoplastic resin composition of a polypropylene-based resin/polystyrene-based resin, excellent in impact resistance, mechanical strength and molding processability and simultaneously having suppressed surface peeling of molded products. CONSTITUTION:A thermoplastic resin composition containing (a) 5-98wt.% polypropylene-based resin containing >=1wt.% modified polypropylene modified with an unsaturated carboxylic acid or its anhydride, (b) 95-2wt.% polystyrene- based resin, (c) an olefinic elastomer modified with an epoxy group-containing monomer in an amount of 5-100 pts.wt. based on 100 pts.wt. total amount of the aforementioned components (a) and (b), and (d) a polystyrene-based block copolymer in an amount of 1-30 pts.wt. based on 100 pts.wt. total amount of the above-mentioned components (a), (b) and (c). |
