ABSTRACT:
A process for the preparation of electrically conductive heteropolyphenylenes, wherein from 0.5 to 5 per cent by weight of an activating additive is introduced, in the absence of moisture and of oxygen, into a heteropolyphenylene of the general formula ##STR1## where X is O, S, Se, SO or SO.sub.2 and Y has one of the meanings given for X or is NH, CH.sub.2, CO or C.sub.6 H.sub.4, and n is from 2 to 250. The activating additive is preferably one of the compounds AsF.sub.5, SbF.sub.5, UF.sub.6, HClO.sub.4, NO.sup.+ SbF.sub.6.sup.-, NO.sub.2.sup.+ SbF.sub.6.sup.-, NO.sup.+ PF.sub.6.sup.-, SbCl.sub.5, NO.sub.2.sup.+ PF.sub.6.sup.-, NO.sup.+ BF.sub.4.sup.-, NO.sup.+ ClO.sub.4.sup.-, (CF.sub.3).sub.2 SO.sub.4, 2,4,6-trinitrophenol, 2,4,6-trinitrophenylsulfonic acid and 2,4,6-trinitrophenylcarboxylic acid, or is sodium, potassium, rubidium, cesium, calcium or barium or one of their amides, the latter being added, if appropriate, in tetrahydrofuran, dimethoxyglycol, anthracene, naphthalene or 2-methylstyrene. The conductive heteropolyphenylenes may be used in the electrical industry for the production of solar cells, for conversion and fixing of radiation and for the production of electrical and magnetic switches, or may be used for the antistatic treatment of plastics.
