  • Patent number: 5204424
    Abstract: Electrically conductive polymers containing repeat units derived from five-membered aromatic heterocyclic monomers substituted, in the 3 position relative to the heteroatom, by an ether-type substituent linked to the heterocyclic ring by an alkylene radical containing at least two carbon atoms. The invention also relates to certain monomers enabling the above-mentioned conductive polymers to be obtained.

  • Patent number: 5149826
    Abstract: A poly[(3-pyrrolyl)acetic acid] is here disclosed which is represented by the formula (I) ##STR1## wherein n is an integer of 2 or more. This polymer can be prepared by subjecting (3-pyrrolyl)acetic acid to electrolytic oxidation polymerization in the presence or absence of a salt. The polymer can be used as a pH sensor in which electrical properties change in accordance with a pH. Furthermore, it can also be used as electrodes for a secondary battery in which a cation transport electrolyte is used.

  • Patent number: 4543306
    Abstract: The invention relates to electrochemical devices and in particular energy storage devices.The object of the invention is the use in such devices of at least one conductive support, covered by a polymer film, obtained by electrochemical polymerization of at least one monomer having at least one aromatic heterocycle with five links containing a single heteroatom, the polymer being in accordance with the general formula: (M.sup.+ X.sup.- y)n. The basic monomer is a pyrrole, thiophene, furan or indole and is substituted by at least one group of the alkyl, alkoxyl, hydroxyl aryl, substituted aryl, halogen, methyl trihalide, cyano, amino or dialkylamino type.
