摘要
研究了邻氯苯胺的电化学聚合和苯环上吸电子取代基氯对聚合物性质的影响。结果表明,苯胺的氨基邻位上引入氯后,单体的电化学聚合速率显著下降,形成的聚合物更易水解。当溶液的pH>1.3时,聚合物的电化学活性完全消失,水解前后,聚合物的紫外可见光谱和红外光谱亦存在差异,聚合物的电子顺磁共振谱是单线结构,水解对聚合物的g因子和△H_(p-p)未发生影响。
The electrochemical polymerization of o-chloroaniline and the effect of the electron-withdrawing halogen in ring-substituted aniline on the properties of the poly-o-chloroaniline have been studied. After chlorine is introduced into the ortho-position of aniline, the polymerization rate of the monomer decreases markedly, the formed polymer is hydrolyzed easily. At pH>1.3, the electroactivities of poly-o-chloroaniline disappear completely. There are a little differences between the UV-Visible and IR spectra of hydrolyzed and unhydrolyzed poly-o-chloroanilines. The ESR spectrum of poly-o-chloroaniline consists of a single narrow line, its g factor and △H_(p-p) are not affected by hydrolysis.
