摘　　要：用PERKIN—ELMER公司的DSC—7仪器测定了改性双马来酰亚胺树脂体系的固化反应。根据DSC测试原理和Arrhenius公式建立的固化反应动力学方程,借助DSC—7动力学软件,求出该树脂体系的固化反应动力学参数—Ea、n、z。利用已得到的动力学参数,进一步预测其固化反应程度(a)、固化反应温度(T)和固化反应时间(t)三者之间的关系。并求出该体系的凝胶化温度(Tgel)、固化温度(Tcure)和后处理温度(Ttreat)的近似数值。The curing reaction of modified bismaleimide resin system was measured with DSC—7 instrument of Perkin—Elmer Company. The kinetyc parameters Ea, n, Z in the curing reaction of the resin system obtained by means of DSC—7 software according to the curing reaction kinetic equation set up by the DSC Measurement Principle and Arrhenius Formula. The relationship among the degree of the curing reaction (α), curing reaction temperature (T) and curing reaction time (t) was further forecasted by use of the obtained kinetic parameters. So, the approximate values for gel temperature (T_(gel)), curing temperature (T_(cure)) and post—treatment temperature (T_(treat)) was calculated.
