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 in which 70% or more of the double bonds have been hydrogenated, the hydrogenated block copolymer (C) having a styrene content of 40 to 80 wt.%, the polybutadiene block Y having a 1,2-bond content of 30 to 80 wt.%, the ratio of the components (A) to (B) being 95:5 to 5:95 by weight, the content of the component (C) being 2 to 30 parts by weight per 100 parts by weight of the components (A) and (B), and 50% or more of the component (C) being present at the interface between the component (A) phase and the component (B) phase. Due to the presence of the component (C), the thermoplastic resin composition can be excellent in heat resistance and oil resistance and have extraordinary tensile elongation properties. |
