摘要
以甲基丙烯酸乙基咔唑酯﹑N-乙烯基咔唑为原料,以偶氮二异丁腈为引发剂,采用共聚合方法合成甲基丙烯酸乙基咔唑酯/N-乙烯基咔唑共聚物。分别用IR﹑UV-vis对其结构进行了表征。利用凝胶渗透色谱仪测定了共聚物的相对分子质量,并讨论了影响相对分子质量的因素,提高引发剂浓度、反应温度都使相对分子质量下降,而延长反应时间则有利于增加相对分子质量。
The methacrylic acid ethyl carbazole ester/N-vinylcarbazole copolymer was synthesized by copolymerization, using methacrylic acid ethyl carbazole ester and N-vinylcarbazole as raw materials, and azobisisobutyronitrile as initiator. Its structure was characterized by UV spectrum and FT-IR. The molecular weight of copolymer was measured by GPC and the influencing factors of molecular weight were discussed.
