In Vitro Hydrolytic Surface Degradation of Poly(glycolic acid):  Role of the Surface Segregated Amorphous Region in the Induction Period of Bulk Erosion

The in vitro hydrolytic degradation of thin (ca. 100 μm) films of poly(glycolic acid) (PGA) has been studied, focusing on the kinetics of degradation of the near surface phases. The emphasis of this work is to describe the nature of the initial “induction” period of hydrolysis of biodegradable polye...
