  • Patent number: 5035926
    Abstract: The invention relates to new polythiophenes containing structural units of the formula ##STR1## in which A denotes an optionally substituted C.sub.1 -C.sub.4 -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.
    Type: Grant
    Filed: April 12, 1990
    Date of Patent: July 30, 1991
    Assignee: Bayer Aktiengesellschaft
    Inventors: Friedrich Jonas, Gerhard Heywang, Werner Schmidtberg, Jurgen Heinze, Michael Dietrich

  • Patent number: 4910645
    Abstract: The invention relates to the use fo polythiophenes which are built up from structural units of the formula ##STR1## in which R.sub.1 and R.sub.2, independently of one another, stand for hydrogen or a C.sub.1 -C.sub.4 -alkyl group, or, together, form an optionally substituted C.sub.1 -C.sub.4 -alkylene radical or a 1,2-cyclohexylene radical, solid electrolytes in electrolyte capacitors, and to the electrolyte capacitors containing these solid electrolytes.
