| 摘 要： | 用动态力学（内耗）和介电方法研究了由蓖麻油（ｃａｓｔｏｒｏｉｌ）、甲苯二异氰酸酯（ＴＤＩ）、丙烯酸羟乙酯（ＨＥＭＡ）组成的网络（Ａｉ）和由正己醇取代Ａ网络中部分ＨＥＭＡ组成的网络Ｂｉ（ｉ＝０，１，２，３）两种网络的内耗及介电损耗，内耗峰强度随悬挂链数目增加而升高，证实了网络破坏后形成的悬挂链的运动对内耗及介电损耗峰高有明显的贡献。

| Abstract: | The motion of molecular in the main transition zone of two kinds of network copolymers, Castor Qil/TDI+HEMA (A_1) and Castur Oil/TDI+HLMA+n Hexamol(B_1) , i=1, 2, 3, has been studied by means of the dynamical mechanical (internal friction) and dielectric methods.In samples B_1, the incernai fraction peak is increasing with the increase of the number of the pedant chains, Comparing with the samples A_i, it is verified that the IF and dielectric loss can be contributed entirely and partly to the motion of the pedant chains in a defective network. |
