Abstract: Stable conductive polymer compositions which do not contain metal ions.The compositions comprise at least one inherently conductive polymer or copolymer chosen from polythiophenes, polypyrroles, polyacetylenes, polyphenylenes, polythiophene copolymers, polypyrrole copolymers and their water-soluble derivatives, characterized in that the inherently conductive polymer is doped with an oxidizing compound chosen from the compounds of formulae:R--NO and R--NO.sub.2,in which R is chosen from the groups HSO.sub.4, R.sup.1 SO.sub.3 and (R.sup.1 SO.sub.2).sub.2 N,in which R.sub.1 ?sic! is chosen from linear or branched alkyl radicals having 1 to 10 atoms, preferably 1 to 4 carbon atoms, and linear or branched fluoroalkyl radicals having 1 to 10 carbon atoms, preferably 1 to 4 carbon atoms. Application in microelectronics.
