Abstract

Thermoplastic mixtures based on macromolecular compounds and pyrrole polymers contain finely divided pyrrole polymers which are embedded in a matrix of the macromolecular compound. Such mixtures are prepared by a process in which solutions of the macromolecular compounds and compounds from the class consisting of the pyrroles are polymerized with an oxygen-containing oxidizing agent, and the resulting mixture is separated off from the solvent. Moldings obtained from such mixtures are used as electrical conductors or as electrodes.
