WIPO Patent Application WO/2011/052252

Kind Code:

A1

Abstract:

Provided is a polylactic acid resin composition wherein the molding cycle is short, the polylactic acid resin exhibits high resistance to hydrolysis, and a superior balance between the hydrolysis resistance and the rigidity of a molded article is achieved. The polylactic acid resin composition is characterized by containing 50 to 98 mass% of a stereocomplex polylactic acid, 1 to 20 mass% of a complex comprising glycidyl methacrylate and silicone/acrylic composite rubber, and 1 to 30 mass% of talc. As a consequence, the molding cycle when molding said polylactic acid resin composition can be shortened, and the molded article formed from said polylactic acid resin composition exhibits both high rigidity and high hydrolysis resistance.
