  • Organometallic polymer compositions useful as constituents of anti-fouling paints for marine structures and their methods of manufacture
    Patent number: 4404328
    Abstract: Organo metallic polymer compositions useful as constituents of anti-fouling paints for marine structures, comprising a main chain consisting of a chlorinated polymer of a conjugated diene monomer such, for example, as a chlorinated polybutadiene of high 1, 2 units content, and at least one grafted chain formed at least partly of recurrent units having a pendant organotin group or tin salt function, wherein the grafted chains also contain recurrent units derived from at least one hydrophilic non-metallic unsaturated organic monomer.
    Type: Grant
    Filed: November 19, 1980
    Date of Patent: September 13, 1983
    Assignee: Institut Francais du Petrole
    Inventors: Francois Dawans, Marguerite Devaud, Denise Nicolas
  • Method of protecting submerged articles against fouling
    Patent number: 4389460
    Abstract: A method of protecting submerged articles from fouling by applying a surface pellicle of a coating substance containing an anti-fouling amount of an organo metallic composition comprising a main chain consisting of a chlorinated polymer of a conjugated diene monomer such, for example, as a chlorinated polybutadiene of high 1, 2 units content, and at least one grafted chain formed at least partly of recurrent units having a pendant organotin group or tin salt function.
