聚乙醇酸的合成、改性与性能研究综述

A Review in Synthesis and Modification of Poly(glycolic acid)

综述了聚乙醇酸(PGA)的合成方法及其单体的制备方法,详细介绍了PGA的物理性能、力学性能、热性能和降解性能,并将其与其他传统塑料进行了对比分析;介绍了PGA的工业化发展进程;阐述了近年来PGA改性方法的研究进展;最后,对PGA加工和改性的技术难点及发展机遇进行了讨论和展望。

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.
