| 摘 要： | The influence of reaction temperature,reaction time, system pressure and catalysts on the re-duced viscosity(η_(sp)/C)and shear viscosity(η_a)of polyglycollic acid(PGA)is given in thispaper.The adequate polymerization condition of glycolide is selected according to the conditionalexperiments.The heat of polymerization and the activation energy at different conversion levelsare also measured by DSC.
