of epoxide and vinyl ether monomers is reported. The inclusion of a small amount of the monomeric photosensitizer is effective in markedly accelerating the cationic photopolymerization of the bulk monomer. Polymers prepared by the polymerization of the monomeric phenothiazine photosensitizers also exhibit excellent photosensitization activity when used in combination with diaryliodonium, triarylsulfonium
描述了几种带有可阳离子聚合的

乙烯基醚和环
氧基团的
吩噻嗪化合物的合成。在鎓盐光
引发剂的存在下,这些单体通过紫外线照射快速有效地聚合或共聚。另外,这些单体同时用作有效的光敏剂,用于鎓盐的光解。在本文中,报道了将这些可聚合光敏剂用于环
氧和
乙烯基醚单体的光聚合。包含少量的单体光敏剂可有效地显着促进本体单体的阳离子光聚合。
