Plasticized polylactic acid and its molded item

摘要: PURPOSE: To obtain a novel improved biodegradable polylactic acid compsn. which is excellent in softness, flexibility, clarity, and gloss without serious detriment to the crystallinity heat resistance hardly exhibits surface staining due exudation of plasticizer. CONSTITUTION: A copolymer mixed with plasticizer wt. ratio (99:1)-(50:50). The formed by copolymn. 99-50wt.% 1-50wt.% polyalkylene ether having mol.wt. 2,000 or higher. mainly comprises (e.g. polyethylene glycol, polypropylene polybutylene ether, their mixture) COPYRIGHT: (C)1996,JPO
