摘要：本文用非等温差示扫描量热法(DSC)结合红外光谱分析,研究了国产聚芳砜原粉热降解过程与在DSC谱图上出现双峰相对应的阶段性机制,用Doyle方程分别测求了热降解两个阶段与总包反应的动力学参数及其补偿效应式。
The kinetics and mechanism of the thermal degradation of polysulfone were studided by non-isothermal differential scanning calorimetry (DSC) and infrared spectra. In the polysulfone DSC diagram two peaks appeared which show that the degradation mechanism of polysulfone devides into two stages. The parameters of kinetics and its compensation effect corresponding to two stages mechanism of degradation were determined with Doyle equation
