Patents by Inventor Gerard Seytre

Gerard Seytre has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polymers containing heterocycles and aromatic nuclei, and conductive organic materials made from such polymers
    Patent number: 4508639
    Abstract: The polymer material is made from a first monomer and from a second monomer. The first monomer Ar includes at least one aromatic nucleus and the second monomer is a five links conjugated heterocyclic ring. The polymer material has the following general chemical formula: ##STR1## in which: X represents the group constituted by sulphur and selenium; R.sub.1 and R.sub.2 are chosen from the group constituted by hydrogen, and by the alkyl, alkoxyl, and hydroxyl groups; and n is the degree of polymerization. Such materials can be made conductive by adding a doping agent, and they can then be used for manufacturing electrodes, junctions, Schottky barriers, etc.
