The crystal nucleating additive for the poly lactic acid compact, production manner and the poly lactic acid compact null poly lactic acid stereo complex of the poly

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid-based molding with excellent transparency and excellent heat resistance in producing the polylactic acid-based molding.;SOLUTION: The crystal nucleating agent comprises a polylactic acid stereocomplex as a main component. The polylactic acid stereocomplex is, for example, produced by dripping a solution of a poly-L-lactic acid and a poly-D-lactic acid to a solvent not to dissolve the poly-L-lactic acid and the poly-D-lactic acid. The average particle diameter of the crystal nucleating agent is preferably ≤500 μm.;COPYRIGHT: (C)2006,JPO&NCIPI
