✦ Synopsis

A chemical polymerization of aniline is quenched a t specific reaction time intervals and the amounts of unreacted aniline and formed p-aminodiphenylamine determined by linear sweep voltammetry. A typical steady state of the p-aminodiphenylamine is observed. Oxidation of aniline to generate p-aminodiphenylamine is the slow step in the polymerization. Furthermore, the t e t r i e r ( ~S C > -N = ~N ~N H . )

of aniline is used as starting material for polymerization under the same conditions as polymerization of aniline. Direct coupling of two tetramers leading to polymer is not observed. A mechanism of polymerization of aniline is proposed.
