    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: Switching and display elements based on ferroelectric liquid-crystals often exhibit a pronounced optical hysteresis which results in the appearance of so-called ghost images. This phenomenon can be markedly reduced or even suppressed if at least one of the two orienting layers are in direct contact with the electrodes and is composed of an electrically conductive polymer of the formula (I): (I) in which R1, R2=independently of each other, H, or straight-chain or branched alkyl or alkoxy containing 1-16 carbon atoms, or halogen, X=S, NH, Y-=BF4-, PF6-, PO43-, AsF6-, SbCl6-, SO42-, HSO4-, alkyl-SO3-, perfluoroalkyl-SO3-, aryl-SO3, F- or Cl-, and n is an integer from 4 to 100 and m is an integer from 1 to 30.

    Abstract: As electroconductive polymers, poly(alkoxythiophenes) are of considerable interest due to their high stability in air and water and their good heat resistance. To prepare such polymers on an industrial scale, an electrochemical process for the preparation of electroconductive poly(alkoxythiophenes) is suitable in which the protons required for the cathode process are available by adding carboxylic acids to conductive salt and electrolyte solvent. The counterions in the doped polymer originate from the conductive salt, so that the properties of the polymer are substantially independent of the proton source.
