摘要：

The polymerization of glycolide and its copolymers with L-lactide was carried out at 150 and 200°C by conventional methods. The copolymer chain microstructure and the trans-esterification process were studied by 1H and 13C NMR spectroscopy, while the thermal properties were determined by differential scanning calorimetry (DSC). Yields of reactions were observed by weighing washed copolymers and by nuclear magnetic resonance (NMR).
