Title:
HYDROLYZABLE COPOLYESTER, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/156346
Kind Code:
A1
Abstract:
Disclosed is a hydrolyzable copolyester. The molecular segment of the copolyester contains a segment of a difficultly hydrolyzable polyester and a segment of an easily hydrolyzable polyester, and the copolyester is a random copolymer or block copolymer composed of the segment of the difficultly hydrolyzable polyester and the segment of the easily hydrolyzable polyester. The copolyester has good strength and toughness, is biodegradable, and can degrade quickly when placed in a natural water environment. Further disclosed is a preparation method for the copolyester, and an application thereof.
