首次用化学法合成了聚N-甲基苯胺(PMAn),系统研究了氧化剂浓度、介质酸浓度、单体(MAn)浓度对聚合反应及所得产物性质的影响。利用FTIR等手段对产物进行了初步表征。结果表明:PMAn具有较高电导和良好的稳定性,其本征态在一系列有机溶剂中可溶,在酸性介质中呈电活性。具有较高电导的产物的链结构主要是1,4-连接的头尾结构,链上同时存在苯式及醌式两种结构单元。
Poly (N-methylaniline) (PMAn) was synthesized by chemical method for the first time. The influences of oxidant concentration, medium acid concentration and monomer (MAn) concentration on the polymerization reaction and the properties of the obtained product were systematically studied. The products were characterized by FTIR and other means. The results show that PMAn has high conductance and good stability. Its eigenstates are soluble in a series of organic solvents and electroactive in acidic media. The chain structure of the product with higher conductance is mainly a 1,4-linked head-tail structure, in which two structural units, benzene and quinone, exist simultaneously.
