Abstract
The invention relates to a process for the preparation of polymers based on polyindoles by chemical polymerization of indole in the presence of an oxidizing agent and of a solvent. The invention also relates to compositions and electroconductive devices containing the polyindoles thus obtained and to the use of the polymers obtained.
