摘　　要：采用热重法(TG)、差示扫描量热法(DSC)测定了全取代五元瓜环(下面简称CYQ[5])在氮气气氛中的热分解过程,结果表明全取代五元瓜环的热分解过程是一个二阶段过程。根据不同升温速率下的热重曲线用多元非线性动力学回归计算,分别得到两个阶段热分解反应的动力学参数Ea、logA及其最概然机理。The thermal decomposition process CYQ [ 5 ] was measured in Nitrogen by means of thermogravimetry and differential scanning calorimetry. The results indicate that the thermal decomposition processes of CYQ [ 5 ] in Nitrogen is a two-stage process. The multivariate non-linear regression method in dynamic analysis to thermal decomposition of CYQ[ 5 ] was used, then factors of kinetics were obtained such as the most probable mechanism function, the activation energy and the pre-exponential factor.
