摘要
我们曾报道过4-甲基丙烯酰氧基二苯甲酮(MABP)与甲基丙烯酸N,N-二甲氨基乙酯(DMAEMA)构成的氧化还原引发体系敏化丙烯腈的光聚合。由于MABP及DMAEMA是可聚合的二芳基酮和脂肪叔胺,因而既能参与引发又能参与聚合而进入聚合物链中。一般二苯甲酮要同三级胺,如三乙胺等一起在紫外光照条件下形成光氧化还原引发体系才能有较好的引发效果。同一分子中既含二苯甲酮基又含三级胺基的光敏剂,
A novel acrylic monomer having acridonechromophore, 2-(N-acridonono)ethyl methacry-late (AEMA) was prepared from methacryloyl chloride and N-hydroxyethyl acridone (HEA), which was obtained by reaction of acridone with ethylene carbonate. Both the monomer and its polymer can initiate the photopolymerization of vinyl monomers, such as AN, MMA etc, but P(AEMA) has higher initiation ability than monomeric AEMA does. The effects of oxygen and aliphatic tertiary amine on the polymerization rate were also revealed. The UV-analysis indicates that AEMA not only initiates photopolymerization of vinyl monomers, but also enters into the polymer chains.
