Structural Evolution of Polyglycolide and Poly(glycolide<i>-co-</i>lactide) Fibers during In Vitro Degradation with Different Heat-Setting Temperatures

Abstract

LA) samples. The introduction of LA units into the PGA skeleton reduced the difference in the degradation rate between the crystalline and amorphous regions, and they were simultaneously degraded in the early stage of degradation, leading to a degradation mechanism different from that of the PGA fiber.
