POLYLACTIC ACID RESIN COMPOSITION AND POLYLACTIC ACID RESIN MOLDED ARTICLE |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition having a sufficiently enhanced crystallization rate and a sufficiently high stereocomplex crystal proportion and a polylactic acid resin molded article obtained by melt molding and crystallizing the polylactic acid resin composition. SOLUTION: The polylactic acid resin composition includes 0.1-20 pts.mass of a fatty acid metal salt represented by chemical formula 1 (wherein R<SP>1</SP>and R<SP>2</SP>are each 7-21C aliphatic hydrocarbon or 7-21C hydroxy aliphatic hydrocarbon; and M is an alkaline earth metal) based on 100 pts.mass of a polylactic acid resin being a polylactic acid blend to form a stereocomplex crystal and/or a polylactic acid stereoblock copolymer.
