Rickey D. Badley 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).

  • Catalyst compositions and catalytic processes
    Patent number: 5852144
    Abstract: Catalyst compositions are provided that comprise (a) discrete silica particles; (b) chromium; and (c) a support comprising silica. These composition are useful in polymerizing ethylene or copolymerizing ethylene with a comonomer and provide better control over the molecular weight and the molecular weight distribution of a resulting polymer.
    Type: Grant
    Filed: September 11, 1997
    Date of Patent: December 22, 1998
    Assignee: Phillips Petroleum Company

  • Ethylene copolymerization process
    Patent number: 5641842
    Abstract: A process is provided comprising copolymerizing, under copolymerizing conditions, ethylene with one or more alpha-olefins, using a catalyst system, where said catalyst system has been sized, to produce a lower-density-copolymer, where said lower-density-copolymer has a density lower than a similar copolymer produced by copolymerizing, under said copolymerizing conditions, ethylene with said one or more alpha-olefins, using said catalyst system, where said catalyst system has not been sized, where said catalyst system that has been sized has had substantially all particles removed that produce, under said copolymerizing conditions, a higher-density-copolymer, where said higher-density-copolymer has a density higher than said similar copolymer.
