  • Method for the manufacture of a polymer reacted with FeCl.sub.3
    Patent number: 4639496
    Abstract: Method for the manufacture of a polymer with triaromatic methane units as basic building blocks, the electric conductivity of which is obtained through the formation of charge transfer complexes. Electron donors and/or electron acceptors are added to the synthetic polymer during or after its preparation, for forming charge transfer complexes.
    Type: Grant
    Filed: August 29, 1985
    Date of Patent: January 27, 1987
    Assignee: Brown, Boveri & Cie AG
    Inventors: Gerd Weddigen, Robert Huber, Birgit Schmidt, Hartmut Schneider
