  • Electroconductive thin film
    Patent number: 4735852
    Abstract: This invention relates to an electroconductive thin film prepared by forming a polymerized thin film on a substrate in a vacuum reactor by the decomposition of a metal complex starting material by glow discharge, said metal complex having a ligand selected from the group consisting of acetylacetonate and at least partially fluorinated acetylacetonate.
    Type: Grant
    Filed: August 5, 1986
    Date of Patent: April 5, 1988
    Assignee: Ricoh Co., Ltd.
    Inventor: Yoshihito Osada
  • Polymerization or inorganic element-containing monomers using plasma, and the formed product
    Patent number: 4320219
    Abstract: An ionized gas plasma is established in an electrical field in contact with a non-vapor volume monomer (liquid and/or solid). The plasma causes polymerization of the monomers which are of the phosphazene or carborane type.
    Type: Grant
    Filed: December 15, 1980
    Date of Patent: March 16, 1982
    Assignee: The Regents of the University of California

  • Method of plasma initiated polymerization
    Patent number: 4212719
    Abstract: An ionized gas plasma is established in an electrical field in contact with a non-vapor volume of monomer (liquid and/or solid). The plasma creates active polymerization sites in the monomer volume to initiate propagation of polymerization therein. After initiation, the partially-polymerized monomer volume is postpolymerized in the absence of the ionized gas plasma to yield a very high molecular weight polymer which may be essentially free of cross-linking in desirable forms including commercial quantities of bulk self-supporting polymer or a coating. Suitable monomers include liquid vinyl monomers (e.g., methyl, methacrylate) and solid crystalline monomers (e.g., 1,3,5-trioxane).

  • Polyion complex and method for preparing the same
    Patent number: 4137217
    Abstract: A fibrous polyion complex or a polyion complex shapable to a mass or a film is prepared by reacting polycation having polymerization degree of not less than 5 or polyamine having polymerization degree of not less than 6 with polycarboxylic acid having polymerization degree of not less than 5. At least one of the reactants may preferably be of long chain polymer if fibrous polyion complex is desired.
