ABSTRACT:
A process for the preparation of a polymer which is electrically conductive and which is based on polythiophene, the process including polymerizing thiophene in a reaction medium including thiophene, from 2.5 to 20 moles of an anhydrous ferric salt per mole of thiophene, from 0.04 to 1 liter of an alkyl halide per gram of thiophene, and from 0.1 to 5% by weight of water introduced into the reaction medium based on the amount of alkyl halide.
