Abstract:
A thermoplastic resin composition comprising:(A) a styrene resin; (B) a propylene resin; and (C) a hydrogenated block copolymer comprising at least two polystyrene blocks X and at least one polybutadiene block Y, with at least 70% of the double bonds of the polybutadiene of the polybutadiene block Y having been hydrogenated, wherein the hydrogenated block copolymer (C) has a styrene content of 45 to 70 wt. %, a 1,2-bound content of the polybutadiene block Y is 30 to 65 wt. %, a weight ratio of the component (A) to the component (B) is 95:5 to 5:95, a content of the component (C) is 2 to 30 parts by weight based on 100 parts by weight of the components (A) and (B), and at least 50% of the component (C) exists at the interference between a phase of the component (A) and a phase of the component (B).
