咔唑衍生物作为引发剂的研究——Ⅱ.N-取代咔唑的合成及其引发甲基丙烯酸甲酯聚合的研究

用不同的方法合成了八种N-取代咔唑。测定了它们的红外光谱和核磁共振波谱。记录了各咔唑衍生物在CCl_4中不同光照时间的紫外-可见光谱。比较了各种咔唑衍生物单组份或与CCl_4组成的双组分体系对甲基丙烯酸甲酯光引发聚合活性。当N-烯丙基咔唑作为引发剂时,它参加了与甲基丙烯酸甲酯的共聚合反应。

POLYMERIZATION OF MONOMERS INITIATED BY CARBAZOLE SYSTEM——Ⅱ. Syntheses and Initiation Activity of Polymerization for Methyl Methacrylate of Carbazole Derivatives

Eight N-substituted carbazole compounds had been synthesized by different methods. Their IR and NMR spectra were measured. UV spectra of their solution in CCl₄ were recorded. The photoinitiation activity of polymerization for methyl methacrylate with these compounds were estimated. Contents of N-allylcarbazole in polymers of methyl methacrylate were analysed.
