摘要
采用热分析-质谱联用技术(TG-DSC-MS)研究了聚3-硝酸酯甲基-3-甲基氧丁环(PNIMMO)热分解过程中质量、能量、气体产物等的变化规律,利用Kissinger法和Ozawa法计算了PNIMMO的动力学参数。计算结果为:Kissinge法,E=179.1 kJ.mol-1、lnA=45.85s-1;Ozawa法,E=177.4kJ.mol-1、lnA=39.19s-1。两种动力学处理方法获得的数据一致。用Coats-Redfern法得到了PNIMMO热分解的机理函数为一级化学反应,并且推测了PNIMMO可能的热分解反应机理。
The whole processes of the PNIMMO thermal decomposition was investigated by using simultaneous DSC-TG-MS. The kinetic parameters of PNIMMO decomposition was obtained from equation Kissinger and equation Ozawa. Equation Kissinge： E= 179.1 kJ·mol^-1, InA= 45.85s^-1, equation Ozawa： E= 177.4kJ·mol^-1. InA= 39.19s^-1 The mechanism functions of PNIMMO decomposition from equation Coats-Redfem was first order reaction. The PNIMMO decomposition gaseous products were studied, the mechanism of PNIMMO decomposition was analyzed.
