%X 采用热重分析法和差示热重分析法研究丙烯腈(AN)接枝热塑性弹性体SIS（SIS-g-AN）的热降解性能。结果得出，SIS-g-AN的平衡起始降解温度、平衡最大降解速率温度和平衡终止降解温度分别为659.17，713.94和740.05 K；热降解反应活化能为195.2 kJ·mol<sup>-1</sup>；热降解机理是Deceleration中的D<sub>3</sub>降解机理；不同质量损失率下的热寿命与温度呈线性关系。;The thermal degradation of SIS-g-AN was investigated by thermogravimetry and differential thermogravimetry.The results showed that the equilibrium temperatures of SIS-g-AN at degradation starting，maximum degradation rate and degradation end were 659.17，713.94 and 740.05 K respectively；the activation energy in thermal degradation process was 195.5 kJ·mol<sup>-1</sup>；the thermal degradation mechanism obeyed D<sub>3</sub> in Deceleration；and the thermal lifetimes at various weight loss rates were linear with temperatures
