摘要
使用热重分析仪(TG)对聚乙丙交酯(PGLA)与聚乙交酯(PGA)的热降解性能进行测试,并通过Kissinger、Flynn-wan-ozawa和Friedman 3种方法计算其降解过程中的活化能Ea。结果表明,PGLA的热稳定性较PGA更好,3种方法均能较好的分析其降解过程,当使用Flynn-wan-ozawa法拟合时,其线性相关性较好。
The thermal degradation for PGLA,PGA was studied using the conventional static and dynamic thermogravimetric techniques in a flowing nitrogen atmosphere.The thermal degradation activation energy E was calculated using kissinger,flnn-wan-ozawa and friedman method respectively,the results show： the stability of PGLAwas much better than PGA,the kissinger and flynn-wan-ozawa could anylasis the degradation dynamics process.
