PROBLEM TO BE SOLVED: To obtain a composition excellent in heat resistance and impact resistance by including a polypropylene resin, a polyphenylene ether resin, a hydrogenated block copolymer and a rubber-reinforced impact-resistant polystyrene resin. SOLUTION: This composition comprises 45-95 wt.% polypropylene resin (A), 55-5 wt.% polyphenylene ether resin (B), 1-30 pts.wt., per 100 pts.wt. total of components A and B, hydrogenated block copolymer (C) obtained by hydrogenating a block copolymer composed of a conjugated-diene-compound-based polymer block CB having a total content of 1,2-vinyl bonds and 3,4-vinyl bonds of a conjugated diene compound of 30-90% and a polymer block CA based on a vinyl aromatic compound and 1-400 pts.wt., per 100 pts.wt. component B, rubber-reinforced impact-resistant polystyrene resin (D) having a rubber polymer having a mean dispersed particle diameter of 0.14-0.70μm. |
