Kenneth Drake has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Coating compositions prepared from lactone-acrylate adduct, polyol and isocyanate
    Patent number: 4618635
    Abstract: Described herein are compositions comprising the reaction product of a polyol, a multi-functional isocyanate, a lactone-acrylate adduct and an hydroxyalkyl acrylate. These compositions are suitable for use as curable coatings.
    Type: Grant
    Filed: May 17, 1985
    Date of Patent: October 21, 1986
    Assignee: Union Carbide Corporation
    Inventors: Claiborn L. Osborn, Joseph V. Koleske, Kenneth Drake
  • Carboxylated poly(oxyalkylenes)
    Patent number: 4528334
    Abstract: Graft copolymers are obtained which are substantially free of insoluble homopolymers by grafting 3 to 15 percent by weight of acrylic acid onto poly(oxyalkylene) compounds.
    Type: Grant
    Filed: April 30, 1984
    Date of Patent: July 9, 1985
    Assignee: Union Carbide Corporation
    Inventors: Robert J. Knopf, Kenneth Drake
  • Amphoteric acrylic ester based latexes
    Patent number: 4451608
    Abstract: Amphoteric acrylic-based latexes are produced by the imination of from about 25% to about 75% of the carboxylic sites of base polymers latexes having an acrylic acid and/or methacrylic acid content of from about 10 to about 35 weight percent, based on the total weight of monomers employed in such base polymers.
    Type: Grant
    Filed: June 30, 1982
    Date of Patent: May 29, 1984
    Assignee: Union Carbide Corporation
    Inventors: Kenneth Drake, Richard A. Hammock
  • Polymer-polyols and polyurethanes based thereon
    Patent number: 4198488
    Abstract: Fluid, stable polymer-polyols are provided which consist of an organic polyol medium and an interpolymer of a minor amount of polymerized ethylenically unsaturated dicarboxylic acid anhydride, such as maleic acid anhydride, and a major amount of at least one different polymerized ethylenically unsaturated monomer, the interpolymer being in the form of particles that are stably dispersed in the polyol. Polyurethane foams produced from these polymer/polyols display improved load bearing and compression set when compared with polymer/polyols produced in a similar manner without the ethylenically unsaturated dicarboxylic acid anhydride; elastomers so produced have improved tensile modulus and tear properties.
