摘要(Abstract)：
聚对苯二甲酰对苯二胺(PPTA)经过紫外光照射后易产生变色，使用氙灯老化箱对PPTA粉体的耐光性能进行研究，使用热重分析方法对PPTA粉体的耐热性能以及热分解动力学进行了研究，通过分析得出PPTA热降解起始分解温度、最大分解速率和热分解动力学参数，这对于了解PPTA热稳定性以及光照条件下老化寿命等具有一定的指导意义。
Poly(p-phthaloyl-p-phenylenediamine)(PPTA) is easy to change color after UV irradiation.The light resistance of PPTA powder was studied by xenon lamp aging box.The heat resistance and thermal decomposition kinetic behavior of PPTA powder were studied by thermogravimetric analysis.Through the analysis,the initial decomposition temperature,maximum decomposition rate and thermal decomposition kinetic parameters of PPTA were obtained,which has certain guiding significance for understanding the thermal stability and aging life of PPTA.
