Abstract

Abstract Translated from German Die Erfindung betrifft neue Polythiophene, enthaltend Struktureinheiten der Formel in der A einen gegebenenfalls substituierten C₁-C₄-Alkylen-­Rest bedeutet, ihre Herstellung durch oxydative Polymerisation der entsprechenden Thiophene und der Verwendung der Poly­thiophene zur antistatischen Ausrüstung von den elek­trischen Strom nicht oder nur schlecht leitenden Sub­straten, insbesondere von Kunststoff-Formteilen und als Elektrodenmaterial für wiederaufladbare Batterien. The invention relates to new polythiophenes containing structural units of the formula in the A represents an optionally substituted C₁-C₄ alkylene radical, their production by oxidative polymerization of the corresponding thiophenes and the use of the polythiophenes for the antistatic treatment of substrates which are not or only poorly conductive in the electric current, in particular of molded plastic parts and as electrode material for rechargeable batteries.
