Jason Roy Kearns 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).

  • Functional organic particles for catalysts supports
    Patent number: 6750303
    Abstract: Functional polymers containing hydroxyl groups as supports for use with catalysts can increase the activity of these catalysts which results in improved ethylene polymerization. The present invention seeks to provide catalysts with improved activity by incorporating 2-hydroxyethyl methacrylate (HEMA) into the support of the catalyst.
    Type: Grant
    Filed: April 30, 2003
    Date of Patent: June 15, 2004
    Assignee: The Governors of the University of Alberta
    Inventors: Peter Phung Minh Hoang, Charles Russell, Jason Roy Kearns, Sieghard E. Wanke, David T. Lynch, Nai-Hong Li
  • Sweet MAO
    Patent number: 6750170
    Abstract: Single site catalysts which contain a transition metal, a cyclopentadienyl may be activated with alumoxanes in the gas, solution or group-containing ligand, and a phosphinimine ligand slurry phase polymerization of olefin. Alumoxanes contain residual aluminum alkyls which may poison the catalysts. The residual aluminum alkyls may be bound and/or removed from the alumoxanes by treatment with carbohydrates such as cellulose, starch or sugar.
    Type: Grant

  • Sweet MAO
    Publication number: 20020086991
    Abstract: Aluminoxanes are used as activators for the gas, solution or slurry phase polymerization of olefins in the presence of single site catalysts. Aluminoxanes contain residual aluminum alkyls which may poison the catalysts. The residual aluminum alkyls may be bound an/or removed from the aluminoxanes by treatment with carbohydrates such as cellulose, starch or sugar.
