Abstract
An electrically conductive composition of (a) at least one oxidized polycationic polyheteroaromatic compound and (b) at least one polyanion of a film-forming thermoplastic polymer containing sulfated alcohol groups ##STR1## in repeating structural units in form of films or filaments is drawn at temperatures below the melt/decomposition temperature to increase electrical conductivity and to improve mechanical properties. The material may be used as electrodes, electrically conductive filaments or components for electromagnetic screening.
