ABSTRACT:
Non-fusible polymers which are insoluble in organic solvents and essentially are of the formula I ##STR1## in which n is 2 or a number greater than 2 and each radical R.sub.1 independently is --H, C.sub.1 -C.sub.20 alkyl, C.sub.1 -C.sub.20 alkoxy, aryl or aryloxy with up to 12 C atoms, aralkyl with up to 20 C atoms, alkaryl with up to 20 C atoms, --CN, --OCOR.sub.2, --OH or --SR.sub.3, in which R.sub.2 and R.sub.3 independently of one another are each C.sub.1 -C.sub.20 alkyl or aryl with up to 12 C atoms, can be used as electrically conductive polymers after doping with oxidizing agents, for example iodine, bromine, SbF.sub.5, AsF.sub.5, PF.sub.5 or SbCl.sub.5.
