  • Patent number: 8546495
    Abstract: Polyaniline is added into a glycidyl group- or isocyanate group-containing (meth)acrylate to obtain a polyaniline-added prepolymer, and then the obtained polyaniline-added prepolymer and another unsaturated group-containing monomer undergo additive copolymerization at their respective double bonds to obtain a polyaniline graft polymer having a weight-average molecular weight of 1,000 to 100,000.

  • Publication number: 20110012065
    Abstract: A method for manufacturing a polyaniline by preparing an aniline mixed solution in which an antirust additive and at least one of aniline and aniline derivatives are mixed and polymerizing at least one of the aniline and the aniline derivatives by adding a polymerization initiator to the aniline mixed solution, polyaniline obtained by the method, a polyaniline-containing solution, and a coating material containing the polyaniline.

  • Publication number: 20100203343
    Abstract: In an antirust treated metal base material in accordance with the present invention, a coating film containing insulating polyaniline in a highly oxidized state (PE state) is formed on the surface of a metal base material. A method for antirust treatment of the surface of a metal base material includes a process of forming a coating film containing insulating polyaniline in a highly oxidized state (PE state) on the metal base material surface. According to the present invention, an antirust treated metal base material, in which the coating film of an insulating polyaniline system containing no dopants exhibits strong corrosion inhibition effect, and a method of antirust treatment for the metal base material are provided.
