TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The electrically conductive layer has a specific resistance of less than 10000 Omega .cm.    TECHNOLOGY FOCUS - POLYMERS - Preparation (Claimed): Preparation of the complex (I) involves oxidatively polymerizing thiophene monomers in the presence of the sulfonated synthetic rubber. The oxidative polymerization of the thiophene monomers takes place in a water-immiscible organic solvent or a mixture of water-immiscible organic solvents. Preferred Composition: The composition comprises water (less than 1 wt.%). Preferred Components: The sulfonated synthetic rubber is a sulfonated synthetic rubber on the basis of hydrogenated or unhydrogenated, optionally partially alkyl-substituted styrene-diene copolymer; sulfonated synthetic rubber on the basis of hydrogenated, optionally partially alkyl-substituted styrene-diene block copolymer; sulfonated synthetic rubber on the basis of hydrogenated, optionally partially alkyl-substituted styrene-butadiene or styrene-isoprene block copolymer (preferably styrene-isoprene block copolymer); or sulfonated styrene-butadiene copolymer, in which at least a portion of the styrene units or at least a portion of the butadiene units or at least a portion of the styrene units and at least a portion of the butadiene units in the copolymer are sulfonated. The functionalized styrene-butadiene copolymer is obtainable by sulfonation of a styrene-butadiene copolymer. The styrene-butadiene copolymer is a block copolymer. The ion-exchange capacity of the sulfonated synthetic rubber is 0.01-5 meq/g. The sulfonated synthetic rubber has a weight-average molecular weight (Mw) determined by gel permeation chromatography of 1000-10000000 g/mol. The polythiophene is a poly(3,4-ethylenedioxythiophene). EXAMPLE - Toluene (45 g) was added to a solution of sulfonated synthetic rubber in cyclohexane (molecular weight of the polymer of greater than 100000 g/mol) (90 g) in a beaker. A Clevios M V2 (RTM: ethylene-dioxythiophene) (9 g) was added. Then, a solution of Fe(III) tosylate in ethanol (47.7 g) was added. The mixture was stirred for 1 hour at room temperature. Then, cyclohexane (450 g) was added. The mixture was stirred for 2 minutes and transferred to bottle. After, work up, poly(ethylene-3,4-dioxythiophene) (PEDOT) having specific resistance of 5 Omega .cm was obtained.
