| 摘 要： | 用差示热分析方法研究反应性和非反应性有机硅改性的环氧树脂热焓松弛行为，并用Ｋｏｈｌｒａｎｓｃｈ－Ｗｉｌｌｉａｍｓ－Ｗａｔｔｓ方程拟合。结果表明，除了自由体积之外、分子链柔顺性是影响物理老化速度的重要因素。

| Abstract: | The enthalpy relaxation behavior of active and non-active polysiloxane modified epoxy resins has been studied by DSC method, and has been curve fitted Kohlransch-Williams-Watts function. The results indicate that besides free volume, flexibility of the Wham plays an important role in influencing the rate of physical ageing. |
