Title:
TOUGHENING DEGRADABLE POLYGLYCOLIC ACID COMPOSITION, AND TOUGHENING DEGRADABLE POLYGLYCOLIC ACID MATERIAL AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/037349
Kind Code:
A1
Abstract:
The present invention relates to the field of polyglycolic acid modification. Disclosed are a toughening degradable polyglycolic acid composition, and a toughening degradable polyglycolic acid material and a preparation method therefor and a use thereof. The toughening degradable polyglycolic acid composition comprises polyglycolic acid, a biodegradable polyester, and a compatibilizer; the biodegradable polyester comprises a biodegradable homopolyester and/or a copolyester; and the compatibilizer comprises at least one of an epoxy compound, a maleic anhydride-grafted polymer, a maleic anhydride polyolefin copolymer, and an isocyanate compound. The composition can increase the toughness of a prepared toughening degradable polyglycolic acid material, and a full-biodegradable material having high toughness is obtained.
