Claim 1

.[.A.]. .Iadd.An electrically conductive polymer .Iaddend.composition comprising .[.(a).]. at least one .[.oxidized.]. polycationic .Iadd.polymer and at least one polyanionic polymer, wherein the polycationic polymer is prepared by electropolymerizing, in a solution with the polyanionic polymer, a monomer selected from the group consisting of aniline, a 3-C 1 -C 12 alkyl-substituted aniline and a .Iaddend.polyheteroaromatic compound which has 5- or 6-membered rings containing 1-3 heteroatoms selected from the group consisting of --O--, --S-- and --N---.Iadd., which rings are either unsubstituted or substituted on the carbon atoms with C 1 -C 16 alkyl .[.or at least one oxidized polycationic aniline or a 3-C 1 -C 12 alkyl-substituted oxidized polycationic aniline.]..Iadd.; .Iaddend.and .[.(b) at least one polyanion of.]. .Iadd.the polyanionic polymer is .Iaddend.a film-forming thermoplastic polymer containing sulfated alcohol groups ##STR43## in repeating structural units.Iadd., .Iaddend.having a glass transition temperature of -100 to +350° C. and a tensile strength of 5 MPa to 1000 MPa.Iadd., the polyanionic polymer being selected from the group consisting of polyesters, polyester amides, polyurethanes, polyamides, polycarbonates, polyimides obtained from hydroxyl-containing monomers, saponified polymers of vinyl esters and ethers, hydroxylated polybutadiene, polyisoprene or polychloroprene, polyacrylates or polymethacrylates containing hydroxyl groups in the ester moiety, polysiloxanes containing hydroxyalkyl groups or reduced polyketones, polyadducts of glycidyl compounds containing on average more than one epoxy group with a diol, and copolymers thereof.Iaddend..
