CRYSTALLINE THERMOPLASTIC RESIN COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a crystalline thermoplastic resin composition capable of providing a molded product excellent in mechanical and optical properties by a smaller amount of an added nucleating agent and to provide a method for producing the resin composition. SOLUTION: This crystalline thermoplastic resin composition is characterized as comprising (A) 100 pts.wt. of a crystalline thermoplastic resin, (B) 0.001-30 pts.wt. of a partial magnesium rosinate and (C) 0.001-30 pts.wt. of magnesium hydroxide or magnesium oxide having 0.5-3.0μm range of average particle diameter. The method for producing the crystalline thermoplastic resin composition is provided.
