Abstract:

This paper reviewed the synthesis routes of poly(glycolic acid) (PGA) and its monomers and compared the mechanical properties, barrier properties, biodegradability, and thermal stability of PGA with other traditional plastics. The development of PGA for the scaled?up production line was also introduced. The modification methods for PGA?based materials were summarized and discussed to provide a critical suggestion on the technical challenges and opportunities for PGA?based materials. With diversity and advanced properties, PGA exhibit great potential to substitute tradition petrochemical?based polymers for high strength and high barrier applications.

Key words: poly(glycolic acid), condensation polymerization, ring?opening polymerization, co?polymerization, blending modification
