ABSTRACT:
Halogen-free polyarylene sulfides which are insoluble in organic solvents and infusible, essentially consisting of structural elements of the formula I ##STR1## these elements being present in the molecule more than five times and in which R is one of the following radicals ##STR2## in which R.sub.1 and R.sub.2 independently of one another are each --H, C.sub.1 -C.sub.20 -alkyl, aryl having not more than 12 C atoms, aralkyl having not more than 20 C atoms, alkaryl having not more than 20 C atoms, --CN, --OCOR.sub.3, --OH or --SR.sub.4, in which R.sub.3 and R.sub.4 independently of one another are each a C.sub.1 -C.sub.20 alkyl or aryl having not more than 12 C atoms, X is NH, NR.sub.5, S or O, in which R.sub.5 is a C.sub.1 -C.sub.20 alkyl or an aryl having not more than 12 C atoms, can be used after doping with oxidizing agents, for example iodine, bromine, SbF.sub.5, AsF.sub.5, PF.sub.5 or SbCl.sub.5, as electroconductive polymers.
