Abstract
Abstract Highly electrically conductive copolymers of pyrroles and alkynes and/or aromatics, which possess good mechanical properties coupled with a well-balanced spectrum of properties, are prepared by anodic polymerization of the pyrroles and alkynes and/or aromatics in a polar solvent in the presence of a suitable conductive salt.
