PROBLEM TO BE SOLVED: To provide a polylactic acid composition, which has considerable hardness as well as rigidity(flexibility) against an external force and gives a highly hard and rigid molded resin structure. SOLUTION: Polylactic acid (p-la) and an olefinic elastomer (Oep) are mixed with the ratio of p-la/Oep=90/10-60/40 in the polylactic acid composition. COPYRIGHT: (C)2006,JPO&NCIPI
