Abstract

Finely divided electrically conductive pyrrole polymers are prepared by a process in which the pyrroles, in solution and in the presence of a conductive salt, are treated with an oxygen-containing oxidizing agent. The finely divided conductive pyrrole polymers can be used for the production of moldings.
