ABSTRACT:
A process for the preparation of electrically conductive hetero-polyphenylenes, having conductivities greater than 10.sup.-2 S/cm, wherein from 0.5 to 35 percent by weight of a strong Lewis acid having a pk.sub.a of from -10 to +4, preferably 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.+ AsF.sub.6.sup.-, NO.sup.+ PF.sub.6.sup.-, NO.sub.2.sup.+ PF.sub.6.sup.-, NO.sup.+ BF.sub.4.sup.-, NO.sub.2.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 or 2,4,6-trinitrobenzoic acid, is added to a hetero-polyphenylene in the absence of moisture and of oxygen.
