中文摘要：

采用甲基丙烯酸乙基咔唑酯（CEM）和N-乙烯基咔唑（NVC）的共聚合反应,合成了具有光导性能的甲基丙烯酸乙基咔唑酯/N-乙烯基咔唑（CEM/NVC）共聚物。讨论了影响共聚组成的因素,并用红外和紫外光谱对产物的结构进行了表征,通过元素分析方法分析了共聚物中各组分的百分含量,采用差示扫描量热（DSC）分析了共聚物的玻璃化温度（Tg）,对掺有C60的CEM/NVC共聚物及聚乙烯咔唑（PVK）的光导性能进行了研究。结果表明,CEM含量增加对共聚物的Tg值降低明显;CEM含量越高,共聚物的Tg越低;共聚物比PVK的成膜性有明显提高;同时其对光导率影响不大。

英文摘要：

2-（carbazol-9-yl） ethyl methacrylate / N-vinylcarbazole（CEM/NVC） copolymer with photoconductivity was synthesized by copolymerized reaction between 2-（carbazol-9-yl） ethyl methacrylate（CEM） and N-vinylcarbazole（NVC）.The influencing factors of copolymer composition were discussed and the structure of product was characterized by infrared and ultraviolet spectrum,and the component content of copolymer was calculated by elemental analysis and the glass transition temperature（Tg） of copolymer was studied by differential scanning calorimetry（DSC）.Photoconductivity of CEM/NVC copolymer doped C60 and poly（N-vinylcarbazole）（PVK） were measured.The results read as follows： Tg of the copolymer is significantly decreased with the increasing percentage of CEM,the film-forming ability of copolymer is enhanced which compared with PVK,at the same time,the photoconductivity of the copolymer is little decreased.
