  • Patent number: 4425465
    Abstract: An aqueous coating composition for the corrosion-protection and/or fire-protection of substrates comprising a dispersion of chemically delaminated vermiculite lamellae in an aqueous solution or dispersion of a film-forming polymeric binder. Preferably the vermiculite lamellae are of size below 50 microns, especially below 20 microns, and the film-forming polymeric binder is in the form of a colloidal dispersion or emulsion of the polymer in water such as is commonly called a latex.
    Type: Grant
    Filed: September 7, 1982
    Date of Patent: January 10, 1984
    Assignee: Imperial Chemical Industries PLC
    Inventors: John C. Padget, Kevin T. McAloon, Anthony J. Burgess
  • Patent number: 4358402
    Abstract: A solid chlorinated polymer product having reduced residual solvent content is prepared by treatment of a solution thereof with steam or hot water in the presence of a separately prepared added chlorinated polymer having a second-order transition temperature at least 20.degree. below that of the chlorinated polymer product which would be obtained in the absence of the added chlorinated polymer.
    Type: Grant

  • Patent number: 4172104
    Abstract: In a process for recovery of a chlorinated polymer from solution in a chlorinated hydrocarbon solvent by treatment with steam or hot water the retention of residual solvent in the product is reduced by carrying out the treatment in the presence in the solution of an ethoxylate of a primary aliphatic alcohol having at least 8 carbon atoms.
