Dispersion Oxidative Polymerization of Pyrrole in Aqueous Solutions of Polyvinyl Alcohol

Resumo

Kinetics of the oxidative polymerization of pyrrole in an aqueous solution of poly(vinyl alcohol) under the action of ammonium peroxydisulfate has been studied. The obtained kinetic data has been quantitatively described with regard to the formation of a new phase, the values of activation energy for the non-catalytic and catalytic stages of the oxidative pyrrole polymerization have been determined. Various mechanisms of oxidative polymerization of pyrrole have been critically evaluated, and the calculated kinetic parameters have been compared with their values available in the literature for oxidative pyrrole polymerization in the absence of stabilizers.
