Patent ID: 7825212

Claim:
A polylactic acid resin composition comprising polylactic acid capable of generating stereocomplex crystallization and an aromatic urea compound represented by formula (1): wherein R 1 represents an alkylene group having 1 to 10 carbon atoms; R 2 represents an alkyl group having 1 to 25 carbon atoms; and m is an integer between 1 to 6, and wherein the polylactic acid capable of generating stereocomplex crystallization is a blend of poly-L-lactic acid and poly-D-lactic acid, and the blend has a ratio of poly-L-lactic acid to poly-D-lactic acid of from 30% to 70% by weight to 70% to 30% by weight based upon a total weight of poly-L-lactic acid and poly-D-lactic lactic acid, or a polylactic acid stereoblock copolymer, wherein the aromatic urea compound is xylylene bisstearyl urea.
