摘要
利用热重分析法(TGA)对自制的碱水易溶聚酯(ASHPET)的热降解动力学进行了研究,并与常规PET和国外某公司碱水易溶聚酯(K-COP)进行了比较。结果表明:几种ASHPET的热稳定性略低于常规PET;三种自制的ASHPET的热稳定性不低于国外某公司的K-COP。
Thermal stability of 3 home-made s （ASHPET） were studied by means of TGA method and was compared with that of PETand K-COP.The results showed;5% weight loss thermal degradation activation energy Eof Ⅰ-COP、Ⅱ-COP、Ⅲ-COP、K-COP and PET are 198.1,212.8,198.4,199.1 and 215.1kj/mol respectively.
