本文综述了乙烯基醚、丙烯基醚和环氧单体的阳离子紫外光固化过程。基于紫外光诱导鎓盐光生酸和光生酸引发的连续聚合的阳离子光聚合最早是在20世纪70年代末提出的。这一进程引起了学术界和工业界的高度兴趣。与类似的自由基介导过程相比，阳离子光诱导具有一些优势，特别是不受氧的抑制、低收缩率、良好的粘附性以及紫外线固化材料的机械性能。此外，所采用的单体通常比广泛用于自由基光聚合的丙烯酸酯和甲基丙烯酸酯毒性和刺激性小。在这篇综述中，特别强调了我们最近对不同类型单体的阳离子光聚合领域的贡献。
This review discusses cationic UV-curing processes of vinyl ethers, propenyl ethers, and epoxy monomers. Cationic photopolymerization based on photogeneration of acid from onium salts induced by UV light and consecutive polymerization initiated by photogenerated acid was first proposed at the end of the 1970s. The process engendered high interest both in academia and in industry. Cationic photoinduction presents some advantages over comparable radical-mediated processes, particularly the absence of inhibition by oxygen, low shrinkage, and good adhesion, and mechanical properties of the UV-cured materials. Moreover, the monomers employed are generally less toxic and irritant than acrylates and methacrylates, which are widely used in radical photopolymerization. In this overview, particular emphasis is given to our recent contributions to the field of cationic photopolymerization for different classes of monomers.
