NOVELTY - An electronic device comprising a layer of a conductive (co)polymer or blend, where anionic polysulfonate moieties are combined with cationic moieties chosen from polythiophenes, polypyrroles and polyanilines, is prepared by addition of a tertiary amine to an aqueous solution or dispersion of the polymer's acidic form, and application of the thus neutralized polymer or polymer blend by a suitable method to form a layer.    USE - Preparation of electronic device e.g. organic FETs, solar cells, organic LEDs, organic photodiodes, or devices comprising organic FET, solar cell, organic LED, and/or organic photodiode, particularly organic LED (all claimed). Can also be used for integrated circuits, displays, radio frequency identification tags, electro- or photoluminescent devices, backlights of displays, charge injection layers, planarizing layers, antistatics, conductive substrates and patterns, photoconductors, electrode photographic applications, and recording materials.    ADVANTAGE - The method enables preparation of electronic devices having improved durability and performance features.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) use of conductive polymer or polymer blend, where anionic polysulfonate moieties are combined with cationic moieties chosen from polythiophenes, polypyrroles and polyanilines, and excess sulfonate ions essentially are counterbalanced by tertiary ammonium ions, for the preparation of an electronic device; and    (2) water-soluble conductive copolymer or blend comprising anionic polysulfonate moieties and cationic moieties chosen from polythiophenes, polyanilines and/or polypyrroles, whose anionic portion is a copolymer combining sulfonic recurring structural units derived from vinylbenzenesulfonic acid, 2-8C alkenylsulfonic acid, (meth)acryloyloxy-2-8C alkylsulfonic acid, (meth)acryloylamido-2-8C alkylsulfonic acid, and/or their salts, with at least 10 wt.% recurring structural units of polyethylene glycol acrylate and/or polyethylene glycol methacrylate.
