Degradation test in vitro was carried out in phosphate buffer solution (0.1M, pH7. 4) at 37 ℃. The buffer solution was changed daily. Degradation test in vivo was implanted the sample to subdermal in adult ICH rat in the scapular area lateral to the dorsal midline. At suitable time the samples were recovered. Molecular weight changes in surface layer and bulk of polymer sample were measured by GPC and weight loss was determined gravimetrically. It was found that the degradation behavior can be regulated by changing the composition of copolymers. The critical compositions from surface to bulk degradation behavior for PGCA, PLCA, PLMCA, PLDCA systems were 15-20, 20-30, 30- 40, 40 of mol percent GA or LA unit in copolymers, respectively. The degradation behavior of PGCA, PLCA, PLMCA, PLDCA systems were compared and analysed. Some factors influencing the degradation character, such as copolymer composition, hydrophobicity, crystallinity and enzyme affect etc. played important role.
