<P>PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition having an enough flowability, that is suitable for molding, and a biodegradability. <P>SOLUTION: The polylactic acid resin composition is produced by combining 1-50 pts.mass polyethylene glycol whose number average molecular weight is 200-20,000 with 100 pts.mass polylactic acid resin whose number average molecular weight is 60,000-70,000, wherein the D-form content of the polylactic acid resin in the polylactic acid resin composition is ≤1.0 mol% or ≥99.0 mol%, and the melt flow rate of the polylactic acid resin composition is 50-150 under a lord of 21.2 N at 190°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
