在室温和高速搅拌下，以十六烷基三甲基溴化铵为相转移催化剂，往咔唑和 50％NaOH水溶液中缓慢滴加1，4－二氯－2－丁炔，反应24h后，经重结晶分离得到 无色针状晶体。IR，~1H NMR，MS，VPO等结构分析方法确定无色针状晶体为反式N －3－炔丁烯基咔唑；加热生成的聚合物为聚炔烃，分子量为1.9-10~3，聚合度为 9；通过DTA－TG分析和热聚合速率的测定，探讨了单体热聚合规律，测得热聚合活 化能为118kJ/mol。聚合物电导率小于10~(-12)S·cm~(-1)，而与FeCl_3形成电荷 转移络合物则达到8*10~(-4)S·cm~(-1)。

N-3-Yne-butenylcarbazole has been synthesized by stirring a mixture of carbazole, 1,4-dichloro-2-butyne, benzene, 50% NaOH and cetyl trimethyl ammonium bromide in water. The compound was polymerized by heating. The polymerization activated energy was 118 kj/mol. Molecular weight of the polymer polymerized at 120 t! was 1.9 x l(r (n ?a9). The conductance ratio of the polymer was less than 10 ~12 S? cm~' and that of the charge transfer compound of the polymer with FeCl3 was 8 x 10 ~4 S ? cm"1.
