Abstract

The action of thermoplastic polymers to whose polymer backbone aliphatic or cycloaliphatic groups are bonded via a group --O--, --O--CO--, --CO--OR.sup.22 --OCO-- or --CO--O--, said aliphatic or cycloaliphatic groups being substituted by Cl, Br and/or iodine in the .alpha.-, .beta.-, .gamma.- or .omega.-position, on an unsubstituted or substituted tetrathio-, tetraseleno- or tetratelluronaphthalene or -tetracene contained in this polymer gives electrically conducting compositions by the formation of charge transfer complexes. These compositions are suitable for the production of antistatic or electrically conducting mouldings, sheets, filaments, fibres, coatings and composites.
