| 摘 要： | 用同步法合成聚丙烯酸甲酯-甲基丙烯酸2-(二甲氨基)乙酯]/环氧树脂(P(MA-DMA)/EP)互穿聚合物网络(IPN),对其力学性能进行了研究,结果表明,该体系IPN由于两网络间接枝导致相客性比较好,动态力学谱仅出现一个转变温度,当P(MA-DMA)/EP=20/80时,力学性能显示正协同效应,对环氧树脂的增韧效果最佳,不同组成比的IPNTg实-Tg计与(d实-d计)差值成正比。

| Abstract: | Simultaneously interpenetrating polymer networks were prepared from polyrmethyl aery-late- 2- (dimethylamino)ethyl methacrylate]/epoxy resin P(MA-DMA )/EP]. Mechanical properties of IPNs were measured. A single glass transition teinperature and a better compatibility were observed. This shows that the sample is the mixed polymer of cross-linking and interpenetrating networks. When P(MA-DMA)/EP= 20/80, there exists positive synergistic. effect. (Tg)calcd was calculated by Fox equation and it was found that (Ts)exp-(Tg)calcd was proportional to (dexp-dcaled). Moreover, the value of (Tg)exp-(Tg) caicd can represent approximately the ratio of interpenetrating to cross-linking. |
