Abstract
Moulding composition in the form of particles of a) at least one polyheteroaromatic compound or an aniline in the oxidised, polycationic form, especially polypyrrole, and b) at least one polyanion of a thermoplastic polymer having sulfated alcohol groups ##STR1## in recurring structural units. Mouldings obtained from the moulding compositions have a high electrical conductivity and good mechanical strength properties. The mouldings can be used as electrodes, electrically conductive fibers or components for electromagnetic screening. The pulverulent moulding compounds are also suitable as electrically conductive fillers for plastics.
