Abstract

Highly electrically conductive copolymers of pyrroles and other heterocyclic compounds having a conjugated .pi.-electron system, which possess good mechanical properties coupled with a well-balanced spectrum of properties, are prepared by anodic polymerization of the pyrroles and other heterocyclic compounds and/or their dimers or oligomers in a polar solvent in the presence of a suitable conductive salt.
