POLYLACTIC ACID-BASED RESIN COMPOSITION, METHOD FOR PRODUCING THE SAME, AND FOAM OBTAINED FROM THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin composition producible of a polylactic acid-based resin foam having both excellent heat resistance and durability (hydrolysis resistance), a method for producing the same, and a foam obtained from the same. SOLUTION: The polylactic acid-based resin composition includes a polylactic acid resin crosslinked by a (meth)acrylic acid ester compound (B) and having terminal carboxy group concentration of 0-5 mol/ton, and a foam nucleating agent (E) including polytetrafluoroethylene as a principal component. The polylactic acid-based resin composition has a melt flow rate of 4-20 g/10 min measured at a load of 2.16 kgf at 190°C. COPYRIGHT: (C)2011,JPO&INPIT
