摘要
Kinetic features of oxidative polymerization of aniline hydrochloride in aqueous media have been analyzed under the assumption of formation of a charge-transfer complex between aniline and quinonediimine fragments of aniline n-mers. The total reaction rate order of the catalytic stage can be between unity and two. The reaction rate order of the catalytic stage in the presence of polyvinyl alcohol is changed from unity to two at heating. Rate constants of the single-electron transfer and the complex formation are independent of the concentration and molecular mass of polyvinyl alcohol.
