POLYLACTIC ACID-CONTAINING THERMOPLASTIC RESIN COMPOSITION AND MOLDED PRODUCT THEREOF

摘要

A polylactic acid-containing thermoplastic resin composition which enables the production of a molded article that can be molded in a practically satisfactory molding cycle and has excellent mechanical properties including impact resistance, excellent heat resistance, excellent weld appearance and the like. The polylactic acid-containing thermoplastic resin composition comprises: 100 parts by weight of a polylactic acid-containing thermoplastic resin component which comprises 50 to 95 parts by weight of a polylactic acid resin (A) and 5 to 50 parts by weight of a rubber-reinforced resin (B); 0.1 to 3 parts by weight of a nucleating agent (C); 1 to 15 parts by weight of a filler (D); and 0.03 to 3 parts by weight of a dispersant (E). The rubber-reinforced resin (B) comprises 30 to 100% by weight of a rubber-containing graft copolymer (b-1) and 0 to 70% by weight of a hard (co)polymer (b-2).
