ABSTRACT:
Method for the preparation of a polymeric shaped article containing an electrically conductive polymer wherein a base shaped article possessing electrically conductive properties is moved along an anode, at least part of the article being in contact with the anode, in the presence of an electrolyte-containing medium containing monomer units, which on polymerization form an electrically conductive polymer and wherein a voltage is applied between the anode and a second electrode which is in contact with the electrolyte-containing medium. It has appeared that, in the method according to the invention, the shaped article does not adhere to the electrode so that the method may be practiced continuously. A further advantage of the shaped article failing to adhere to the electrode is that the method according to the invention generates very little waste. Furthermore, it has appeared that the method according to the invention allows a shaped article to be produced with a very short polymerization time, the electrically conductive polymer in which being homogeneously distributed. The applied base shaped article does not swell during wetting, so that the mechanical properties of the base shaped article do not deteriorate. As a result, if the method is applied, for instance, continuously, a higher rate of production can be applied.
