POLYLACTIC ACID-BASED THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid-based thermoplastic resin composition capable of providing a molded article having good appearance and excellent in physical properties such as shock resistance or heat resistance and the like, and the molded article thereof.SOLUTION: There is provided a polylactic acid-based thermoplastic resin composition containing 100 pts.wt. of (A) a polylactic acid resin of 10 to 40 pts.wt., (B) aromatic polycarbonate of 30 to 85 pts.wt., (C) a rubber-containing graft copolymer obtained by graft copolymerizing an acrylic monomer with a rubbery polymer of 5 to 30 pts.wt. and 1 to 50 pts.wt. of (D) polycarbonate containing an isosorbide structure. There is also provided a polylactic acid-based thermoplastic resin molded article obtained by forming the polylactic acid-based thermoplastic resin composition.
