摘要
为了探讨苯胺聚合机理和苯环上不同取代基对聚苯胺性质的影响,我们将十六种邻、间、对位苯胺衍生物的盐酸溶液进行了恒电位电解,电解时,以0.1V为间隔从0.3V上升到1.20V(vs.SCE).十六种行生物中,取代基为氯的衍生物有对氯苯胺、邻氯苯胺、2,4-二氯苯胺和2,5-二氯苯胺;取代基为甲基的衍生物有对甲苯胺和邻甲苯胺.电解结果,仅发现邻氯苯胺和邻甲苯胺能在阳极铂片上聚合成蓝色的膜,但邻氯苯胺的聚合速度非常慢。本文通过循环伏安法、紫外可见光谱、ESR和磁化率的测定研究了聚邻甲苯胺的物理化学性质.
The changes in potentials and pH values of the solution gave rise to variationsof colour and electronic absorption spectra of poly-o-methylaniline film. However,its colour did not change with potential and polymer lost its electrochemical activi-ties in the solution of pH 4.13. The g-value was 2.0027 and was not affected by thekinds of doped anions and hydrolysis. The ΔH_(p-p) was 1.6G. It did not depend onthe kinds of doped anions, but was affected by hydrolysis. The magnetic suscepti-billity of poly-o-methylanlline was not measurable at 0.8 to 4kG magnetic field.
