Monomeric and Polymeric Phenothiazine Photosensitizers for Photoinitiated Cationic Polymerization

摘要: The syntheses of several phenothiazine compounds bearing cationically polymerizable vinyl, vinyl ether and epoxide groups are described. These monomers were rapidly efficiently polymerized or copolymerized by UV irradiation in the presence onium salt photoinitiators. In addition, simultaneously function as efficient photosensitizers for photolysis salts. this article, use these photopolymerizations is reported. inclusion a small amount monomeric photosensitizer effective markedly accelerating cationic photopolymerization bulk monomer. Polymers prepared polymerization also exhibit excellent photosensitization activity when used combination with diaryliodonium, triarylsulfonium, dialkylphenacylsulfonium
