POLYPROPYLENE-SYNDIOTACTIC POLYSTYRENE RESIN COMPOSITION

摘要

PURPOSE: A polypropylene-syndiotactic polystyrene thermoplastic resin composition is provided, to improve the compatibility of a polypropylene resin and a syndiotactic polystyrene polymer and have good impact resistance and heat resistance. CONSTITUTION: The thermoplastic composition comprises a resin composition which consists of (A) 50.0-95.0 wt% of polypropylene and (B) 50.0-5.0 wt% of syndiotactic polystyrene, and also comprises on the basis of 100 part by weight of the resin composition, (C) 1.0-10.0 part by weight of polyamide or polybutylene terephthalate as a thermoplastic engineering polymer and (D) 1.0-10.0 part by weight of a compatibilizer and other additives.
