Patents by Inventor Marjorie King

Marjorie King 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 monitoring and control using improved leading indicators
    Publication number: 20050267267
    Abstract: Embodiments of our invention relate generally to methods of monitoring and controlling polymerization reactions including reactions producing multimodal polymer products using multiple catalysts in a single reactor. Embodiments of the invention provide methods of rapidly monitoring and controlling polymerization reactions without the need to sample and test the polymer properties. The method uses reactor control data and material inventory data in a mathematical leading indicator function to control the reactor conditions, and thereby the products produced under those conditions.
    Type: Application
    Filed: September 28, 2004
    Publication date: December 1, 2005
    Inventors: David Sandell, Marjorie King, Fred Ehrman
