Abstract

The invention relates to dispersions of polythiophenes made up of structural units corresponding to the following formula ##STR1## in which R.sub.1 and R.sub.2 independently of one another represent hydrogen or a C.sub.1-4 alkyl group or, together, form an optionally substituted C.sub.1-4 alkylene group, PA2 in the presence of polyanions, to the production of these dispersions and to their use for the antistatic treatment of plastic mouldings.
