摘　　要：运用傅立叶红外光谱(FTIR)技术对NPN和IPN的谱图进行分析可知,两种硝酸酯的红外光谱图非常相似。通过DSC测试NPN、IPN热分解过程,得到了两种硝酸酯热分解的动力学参数。通过分析比较三个温度下的速率常数和热分解时的峰温,得出IPN的热安定性略低于NPN的结论。The infrared spectra of NPN and IPN were very similar measured using FTIR. The kinetic pa rameters of the thermal decomposition of two nitrates were obtained using DSC. It shows that the thermal stability of IPN is slightly lower than that of NPN according to the rate constants at different three temperature and peak temperatures of thermal decomposition.
