Moses Olukayode Jejelowo 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).

  • Polymerization catalysts, their production and use
    Patent number: 6143854
    Abstract: The invention generally relates to a catalyst, particularly a metallocene catalyst and catalyst system useful in the polymerization of olefins into a polymer product. The polymer product has a broad molecular weight distribution, a high molecular weight and a narrow composition distribution and is easily processable.
    Type: Grant
    Filed: June 24, 1996
    Date of Patent: November 7, 2000
    Assignee: Exxon Chemical Patents, Inc.
    Inventors: Robert Lee Bamberger, Moses Olukayode Jejelowo
  • Polymerization catalysts, their production and use
    Patent number: 6136930
    Abstract: The invention generally relates to a catalyst, particularly a metallocene catalyst and catalyst system useful in the polymerization of olefins into a polymer product. Specifically, a catalyst system with (n-PrCp).sub.2 ZrCl.sub.2 exhibits high catalytic activity.
    Type: Grant
    Filed: May 26, 1998
    Date of Patent: October 24, 2000
