PURPOSE: A syndiotactic polystyrene resin composition obtained by applying syndiotactic polystyrene-maleic acid anhydride and hydrogen added styrene/butadiene/styrene-maleic acid anhydride as a rubber component and compatibilizing agent to a syndiotactic polystyrene-containing composition is provided, which has excellent mechanical physical properties and in particular impact resistance. CONSTITUTION: The polystyrene resin composition comprises 50 to 95 parts by weight of syndiotactic polyestyrene, 2 to 20 parts by weight of a hydrogen added styrene/butadiene/styrene block copolymer (SEBS), (C) a hydrogen added styrene/butadiene/styrene-maleic acid anhydride (SEBS-MA), (D) 1 to 10 parts by weight of polyphenyleneoxide (PPO), (E) syndiotactic polyestyren-maleic acid anhydride (sPS-MA), (F) 0.02 to 20 parts by weight of a diamine compound and additionally adding 5 to 30 parts by weight of glass fiber. |
