  • Control of resin properties
    Patent number: 6846884
    Abstract: A method for controlling resin properties during the production of polyolefins is provided. The method utilizes coordinated manipulation of reaction temperature in combination with a secondary process variable to control resin flow properties to rapidly respond to manufacturing upsets or specification changes to minimize off-grade or transition polymer material when moving from one polymer grade to another, or during a disturbance in a steady state production.
    Type: Grant
    Filed: September 27, 2002
    Date of Patent: January 25, 2005
    Assignee: Union Carbide Chemicals & Plastics Technology Corporation
    Inventors: John R. Parrish, Ivan J. Hartley, Lonnie L. Pinson
