TOUGHENING DEGRADABLE POLYGLYCOLIC ACID COMPOSITION, AND TOUGHENING DEGRADABLE POLYGLYCOLIC ACID MATERIAL AND PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

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.
