Abstract:

This article offers a comprehensive and systematic review for recent advances in the modification of poly(glycolic acid) (PGA), with a focus on copolymerization and blending strategies. The review examines the design of block and random copolymers and discusses how different copolymerization systems influence the crystallinity, mechanical properties, and degradation behavior of PGA. Additionally, the review highlights recent work on blending PGA with other polymers, emphasizing methods to improve toughness and enhance processability through physical blending.

Key words: biodegradable, polyesters, polyglycolic acid, copolymerization modification, blending modification
