Abstract: A coating composition comprising a soluble oligomer of substituted thiophenes with or without a soluble polymer produces, on application from solution in a dipolar aprotic solvent, firmly adhering electrically conductive coats on non-conducting or semiconducting materials. In this way it is possible to produce antistatic films and fibres and shapes for the purposes of electronics and electrical equipment.

Abstract: A coating composition comprising a soluble electroconductive polymer of substituted thiophenes and, if appropriate, a soluble non-conductive polymer produces, when applied from the solution in an aprotic solvent, highly adherent, electroconductive coatings on non-conductive or semiconducting materials. In this way, antistatic films and fibers and mouldings for the purposes of electronics and electrics can be produced.

Abstract: The invention relates to oligomers which are intrinsically electrically conducting and comprise three to ten structural units, which are completely soluble, in the oxidised form, in dipolar aprotic solvents at room temperature, and which also contain structural units derived from at least one monomer of the formula (I) in which R is a C1-C12-alkoxy group or -O(CH2CH2O)nCH3 where n = 1 to 4 and R is a hydrogen atom, a C1-C12-alkyl group, a C1-C12-alkoxy group or -O(CH2CH2O)nCH3 where n = 1 to 4, or R together with R is -O(CH2)m-CH2 or -O(CH2)m-O- where m = 1 to 12. The invention relates furthermore to a process for the preparation of these oligomers by electrochemical polymerisation of at least one monomer of said formula (I) in the presence of an electrolyte solvent and a conductive salt, the anode consisting of carbon and having a specific surface area of at least 0.02 m /g and a network (reticulated), sponge, fabric or felt structure; the electrolyte is a dipolar aprotic solvent, the electrolyte system is not moved or is moved only slightly relative to the anode, the reaction temperature is in the range from -60 to 80@C and the monomer concentration is from 0.01 to 5 mol/l of electrolyte solvent. The oligomers according to the invention can be employed with particular suitability for coating purposes.

Abstract: In conventional electrically conducting polymers in the oxidised (doped) form, the anions can be replaced as desired if the polymer in solution is combined with a salt which contains the proposed anion and the solution equilibrium is adjusted taking into account the solubility products of the salts present. In this way, the properties of the electrically conducting polymers can be tailored to various applications.

Abstract: The intrinsically electrically conductive polymers, preferably oligomers, are, in the oxidised form, fully soluble in dipolar aprotic solvents at room temperature and contain structural units derived from at least one monomer of the formula (I) in which R is a C1-C12-alkoxy group or -O(CH2CH2O)nCH3 where n = 1 to 4 and R is a hydrogen atom, a C1-C12-alkyl group, a C1-C12-alkoxy group or -O(CH2CH2O)nCH3 where n = 1 to 4, or R and R together are -(OCH2)m-CH2 or -O(CH2)m-O- where m = 1 to 12. These polymers are prepared by electrochemical polymerisation of at least one monomer of this formula (I) in the presence of a conductive salt, where the anode has a specific surface area of at least 0.01 m /g and preferably has a grid, sponge, woven or felt structure, the electrolyte solvent is dipolar and aprotic, and the electrolyte system is only agitated gently, or not at all, relative to the anode. The polymers according to the invention are particularly suitable for coating purposes.
