Carbazole monomers bearing cationically polymerizable vinyl, vinyl ether and epoxide groups are rapidly and efficiently polymerized by UV irradiation in the presence of onium salt photoinitiators. Moreover these monomers were observed to function as efficient photosensitizers for the photolysis of the onium salts. In this article, the use of these polymerizable photosensitizers for the photopolymerizations of epoxide and vinyl ether monomers is reported. The inclusion of only a small amount of the monomeric carbazole photosensitizer is effective in markedly accelerating the photopolymerization of the bulk monomer. The broadening of the spectral response through the use of these photosensitizers accounts for the observed rate enhancement of these polymerization reactions. Polymers prepared by the polymerization of the monomeric photosensitizers also exhibit excellent photosensitization activity. References: 37
