Abstract

The invention relates to a process for the preparation of electrically conductive polymers derived from 3-alkylthiophenes by chemical polymerization of the 3-alkylthiophene by means of a ferric salt, an alkyl halide and water. The invention also relates to electrically conductive devices containing the poly(3-alkylthiophenes) obtained and a thermoplastic polymer.
