本文涉及的电化学聚合均用在线紫外—可见光谱进行跟踪，结果表明电化学共聚随着反应体系中邻氨基苯甲酸的浓度的增加而变慢；同时，在电化学聚合过程中的电流—时间瞬时响应曲线表明聚邻甲基苯胺和共聚物均可能是以三维累积成核的方式沉积在ITO导电玻璃电极上。

In the inductive period of the polymerization, the rate is proportional to the second power of the potential, but in the autocatalytic period, the rate is only proportional to the potential.
