Abstract

A process for the preparation of electrically conductive polyaromatics having conductivities greater than 10.sup.-2 S/cm, wherein from 0.5 to 15% by weight of an oxidizing Lewis acid, e.g. antimony pentafluoride or arsenic pentafluoride, or their NO.sup.+ - or NO.sub.2.sup.+ -salts, or a nitroaromatic, e.g. trinitrophenol or trinitrobenzenesulfonic acid, and/or a fluorine derivative, e.g. CF.sub.3 --COOH, or an acid, e.g. sulfuric acid, nitric acid or perchloric acid, is added to a polyaromatic, in the absence of moisture.
