Title:
ポリ乳酸組成物、ポリ乳酸組成物から得られる成形体、およびポリ乳酸組成物の製造方法
Document Type and Number:
Japanese Patent JP6771380
Kind Code:
B2
Abstract:
Even when a tin-based polymerization catalyst and a phosphorus-based compound are present in a poly-L-lactic acid (A) and a poly-D-lactic acid (B), by using a specific proportion of an organic acid metal salt or an organic metal salt for stereocomplex crystallization, a stereocomplex polylactic acid composition having a high stereocomplex crystallinity and a high stereocomplex crystal melting point, a small stereocomplex crystal melting point depression even after remelting, a small decrease in the molecular weight, excellent forming processability, and also heat resistance can be provided.
