摘　　要： 采用非等温热重法对聚苯硫醚的热分解动力学进行研究,通过比较计算结果选定拟合结果更好的迭代法计算反应活化能,采用积分法结合36种动力学函数来判断聚苯硫醚热分解的机理函数。得到了聚苯硫醚热分解动力学参数平均活化能E、指前因子A和对应的热分解动力学方程。 Non-isothermal thermograviraetry was used to study the thermal decomposition kinetics of polyphenylene sulfide （PPS）. By comparison of fitting results with that of KAS method and FWO method,the iterative procedure method was employed to calculate the activation energy E based on its better fitting resuits. Integral method with 36 types of kinetic function was proposed to define the most probable kinetic function. The decomposition kinetic parameters were determined, which the most probable kinetic function belonged to G（α） = （1 -α） ^-1/2- 1 ,the average activation energy E,the pre-exponential A and the corresponding thermal decomposition dynamic function were obtained.
