Abstract:

This paper introduced the basic principles of modification methods and principles for the processing process of poly(glycolic acid) (PGA) from the aspects of its physical properties, processing techniques, and practical applications. The paper mainly reviewed the current research progress in modification methodologies through plasticization, toughening, and copolymerization, including the usage of different additives such as compatibilizer EMA⁃GMA, chain extender ADR and plasticizer. The effects of these additives were concluded and compared. The compatibility of varied toughening agents with PGA material and the strengthening technology of interface mutual diffusion were discussed. Finally, the modification rules for PGA processing as well as its application performance were summarized.

Key words: poly(glycolic acid), modification, degradation, application
