Novel polythiophenes, process for their preparation, and their use

摘要

The invention relates to polythiophenes, built up from structural units of the formula <IMAGE> in which A is an optionally substituted C1-C4-alkylene radical, their preparation by oxidative polymerisation, and a process for the antistatic finishing of substrates which conduct electrical current only poorly or not at all which comprises producing these polythiophenes by oxidative polymerisation on the surface of these substrates.
