  • Electroconductive organic polymer and method for producing the same
    Patent number: 4615829
    Abstract: An electroconductive organic polymer exhibiting outstanding electroconductivity is described, containing an electron acceptor as a dopant, and having electroconductivity of not less than 10.sup.-6 S/cm, substantially comprising a linear polymer having as a main repeating unit thereof a quinonediimine structure represented by formula (III) ##STR1## wherein R represents a hydrogen atom or an alkyl group. This polymer can be obtained by oxidative polymerization of an aniline compound or a water-soluble salt thereof with an oxidizing agent in a reaction medium containing a protonic acid.
    Type: Grant
    Filed: November 13, 1984
    Date of Patent: October 7, 1986
    Assignee: Nitto Electric Industrial Co., Ltd.
    Inventors: Shohei Tamura, Sadamitsu Sasaki, Masao Abe, Hitoshi Nakazawa, Hisashi Ichinose, Keiji Nakamoto, Satoshi Yumoto
  • Electroconductive porous film and process for producing same
    Patent number: 4556623
    Abstract: An electroconductive porous film is described comprising a porous film substrate having deposited thereon an electroconductive organic polymer containing an electron acceptor as a doptant, substantially comprising a linear polymer having as a main repeating unit thereof a quinonediimine structure represented by formula (III). ##STR1## wherein R.sub.1 and R.sub.2, which are the same or different, each represents a hydrogen atom or an alkyl group.
