Patents by Inventor Galen Richard Hatfield

Galen Richard Hatfield 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).

  • Regio-regular copolymer and methods of forming same
    Patent number: 6506860
    Abstract: A new and novel linear, regio-regular vicinal functionalized polymer methods of forming the same are described. The polymer has a linear hydrocarbon polymer backbone with vicinal functional groups having oxygen and/or nitrogen atom containing groups, such as hydroxy, carboxylic acid or ester, carbonyl acetate, amide, nitrile and the like, pendent from the polymer backbone chain in a regio-regular manner.
    Type: Grant
    Filed: September 28, 2000
    Date of Patent: January 14, 2003
    Assignee: Cryovac, Inc.
    Inventors: Donald Albert Bansleben, Truc-Chi Thi Huynh-Tran, Rusty Lew Blanski, Paul Anthony Hughes, William Peyton Roberts, Robert Howard Grubbs, Galen Richard Hatfield
  • Narrow molecular weight distribution copolymers containing long chain branches and process to form same
    Patent number: 6313241
    Abstract: The subject invention is directed to new and novel copolymers having long chain branches formed from ethylene and at least one vinyl alicyclic monomer, to solution polymerization using certain unstrained bridged metallocene catalyst which has been found capable of forming said copolymers and to packaging material formed therefrom.
    Type: Grant
    Filed: October 1, 1997
    Date of Patent: November 6, 2001
    Assignee: Cryovac, Inc.
    Inventors: William John Gauthier, Ronald Dean Moffitt, Galen Richard Hatfield
  • Regio-regular functionalized polymeric packaging material
    Patent number: 6203923
    Abstract: The present invention is directed to Packaging Materials and Packaging Articles having a structure composed of a substantially linear, regio-regular functionalized hydrocarbon polymer having C4-C12 hydrocarbon polymer repeating units wherein each unit has at least one functional group uniformly pendent therefrom.
    Type: Grant
