  • Water-soluble carbamate materials
    Publication number: 20020103319
    Abstract: The invention provides water-soluble, &bgr;-hydroxy carbamate-functional materials and coating compositions, especially waterborne coating compositions, containing the carbamate-functional materials. The invention further provide a coating prepared from the coating composition and a coated substrate, especially an automotive substrate, having the coating thereon.
    Type: Application
    Filed: January 9, 2002
    Publication date: August 1, 2002
    Inventors: Walter H. Ohrbom, David J. Law, Patricia A. Herrel
  • Waterborne coating compositions containing materials dispersed with water-soluble carbamate materials
    Publication number: 20020086966
    Abstract: The invention provides an aqueous coating composition containing a dispersed, emulsified, or dissolved material (organic compound, resin, or polymer), in which the material is dispersed, emulsified, or dissolved with a water-soluble, carbamate-functional material. The invention further provides a coating prepared from the coating composition and a coated substrate, especially an automotive substrate, having the coating thereon.

  • Monomer and polymerization process
    Publication number: 20020035289
    Abstract: The &bgr;-hydroxy carbamate, ethylenically unsaturated monomer of the invention can be polymerized as a homopolymer or copolymerized with other monomers. The polymerization can be carried out in an aqueous medium. The &bgr;-hydroxy carbamate monomer is polymerized to form water-soluble homopolymers or, if polymerized as a mixture with one or more comonomers, copolymers that are soluble, emulsifiable, or dispersible in water. The &bgr;-hydroxy carbamate monomer can be used as a replacement monomer for acrylamide.
