| 摘 要： | 科学技术的进步,对新材料的要求逐步向着多功能和高性能的方向发展,单组分材料已难于满足这种要求,在高分子材料方面,人们采用了共混、接枝、嵌段等方法以达到改善和提高性能的目的。感光性高分子是一类很重要的功能材料,至今,大部分采用自由基聚合方式制备。近年来,阳离子引发体系发展很快,特别鎓盐光引发体系受到很大的重视,发展迅速。

| Abstract: | A photoinduced concurrent radical-cationic polymerization hybrid system composed of epoxy resin 618/epoxy resin 6101/acrylate with diphenyliodonium salt as photoinitiator was studied. Under UV irradiation the radical and cationic polymerization was carried out simultaneously. The rate constants of radical and cationic photopolymerization of acrylate and epoxy components were determined by infrared spcctrometry, gelatinfraction and hardness respectively. The results obtained show that the acrylate is more reactive related to epoxy component. Evidently the rate of photocuring increases with increasing degree of epoxy content. Such hybrid systems may provide greatly flexibility in formulating UV-curable compositions toward the goal of achieving desirable properties and application. |
