Polythiophenes, process for their preparation and their use

摘要

The invention relates to new polythiophenes containing structural units of the formula (I) in which A denotes an optionally substituted C1-C4-alkylene radical, their preparation by oxidative polymerization of the corresponding thiophenes and the use of the polythiophenes for imparting antistatic properties on substrates which only conduct electrical current poorly or not at all, in particular on plastic mouldings, and as electrode material for rechargeable batteries.
