ELECTROCHEMICAL PROCESS FOR THE PRODUCTION OF ELECTRICALLY CONDUCTING POLY(ALKOXYTHIOPHENES) WITH CARBOXYLIC ACIDS ADDED

摘要

Electrochemical process for the production of electrically conducting poly(alkoxythiophenes) with carboxylic acids added. Poly(alkoxythiophenes) are of great interest as electrically conducting polymers as a result of their high stability towards air and water and as a result of their good temperature resistance. Suitable for the production of such polymers on an industrial scale is an electrochemical process for the production of electrically conducting poly(alkoxythiophenes) in which the protons needed for the cathode process are made available by adding carboxylic acids to conducting salt and electrolyte solvent. The counterions in the doped polymer originate from the conducting salt, with the result that the properties of the polymer are substantially independent of the proton source.
