摘要
通过测定升温固化过程的ＤＳＣ曲线，研究了４，４′－二氨基二苯砜（ＤＤＳ）／环氧端基酚酞聚芳醚腈（简称Ｅ－ＰＣＥ树脂）固化体系的热效应；测算了固化反应过程的表观活化能及反应级数。另外，通过差示扫描量热（ＤＳＣ）和热解重量分析（ＴＧＡ）测试了固化后试样的热性能。
According to the DSC curves of the heating cure procedure, the authors studied the heat effect of the E-PCE/DDS curing system,calculated the apparent activation energy and the reactive order.In addition, the heat-resistant quality and aging resistance of the fully crosslinked E-PCE/DDS were also measured by DSC and TGA.
