Title:
FLEXIBLE POLY(LACTIC ACID) RESIN COMPOSITION CONTAINING WATER SCAVENGER
Document Type and Number:
WIPO Patent Application WO/2017/135618
Kind Code:
A1
Abstract:
The present invention relates to a novel flexible poly(lactic acid) resin composition, wherein the flexible poly(lactic acid) resin composition contains a block copolymer, a catalyst, and a water scavenger and thus can achieve a high degree of polymerization of a poly(lactic acid) resin even without a separate water removal process. In addition, the poly(lactic acid) resin prepared of the poly(lactic acid) resin composition exhibits excellent hydrolysis resistance; excellent general properties, such as mechanical properties, transparency, heat resistance, blocking resistance, and bleed-out resistance; and improved flexibility, and thus can be favorably used as a packaging material.
