(57) [Summary] [Purpose] To provide a syndiotactic polystyrene resin composition having a significantly improved impact resistance, elongation, and physical property retention in recycling without impairing heat resistance and elastic modulus. [Structure] (a) 100 parts by weight of SPS, (b) 1 to 100 parts by weight of a high molecular weight material composed of 5 to 95% by weight of PPO and / or modified PPO and 95 to 5% by weight of a rubber-like elastic material, and optionally (d) 1 to 350 parts by weight of an inorganic filler. With respect to 100 parts by weight of the polystyrene resin composition and the component (a), the component (b) is 0.1 to 3 A polystyrene resin composition comprising 0 parts by weight, (c) 1 to 100 parts by weight of a rubber-like elastic body, and optionally 1 to 350 parts by weight of component (d). |
