Kinetics and mechanism of oxidative polymerization of phenylenediamines

Kinetics of oxidative polymerization of three isomeric phenylenediamines in aqueous hydrochloric acid solutions initialed by ammonium persulfate has been studied, and kinetic parameters of non-catalytic and catalytic stages of polymerization have been determined. The observed effect of the isomeric substrates structure on the activation energy of the catalytic and non-catalytic stages has been explained.
