The invention relates to novel polythiophene-polyanion complexes which are soluble or dispersible in nonpolar organic solvents, and to the use thereof.

Polythiophene polyanion complexes in homopolar organic solvents

The invention relates to a process for producing electrolyte capacitors with high capacitances and low equivalent series resistance, to electrolyte capacitors produced by this process and to the use of such electrolyte capacitors.

Method for producing solid electrolyte capacitors

The present invention relates to novel processes for preparing an aqueous or nonaqueous dispersion or solution comprising at least one conductive polymer and at least one polyanion, characterized in that the polymerization is performed at a pressure below atmospheric pressure, to aqueous or nonaqueous dispersions or solutions prepared by this process and to the use thereof.

Process for producing conducting polymers

The present invention provides a method for the production of an aqueous dispersion containing an electroconductive polymer component which enables electroconductive thin films which are outstanding in their transparency and electroconductivity to be formed, together with the aqueous dispersion obtained by said method. This method includes a stage in which a 3,4-dialkoxythiophene is polymerized in an aqueous solvent using an oxidizing agent in the presence of a polyanion and, in this stage, said oxidizing agent is added by the dropwise addition of a solution or dispersion containing said oxidizing agent to the reaction solution or, alternatively, in the polymerization stage, the alkali metal ion concentration in the reaction liquid is maintained at no more than 400 ppm.
