  • Bimodal polyolefin production process and films therefrom
    Patent number: 6943134
    Abstract: A process of producing a bimodal polyolefin composition is described, which includes in one embodiment contacting monomers with a supported bimetallic catalyst composition for a time sufficient to form a bimodal polyolefin composition that includes a high molecular weight polyolefin component and a low molecular weight polyolefin component; wherein the supported bimetallic catalyst includes a first catalyst component that is preferably non-metallocene, and a second catalyst component that includes a metallocene catalyst compound having at least one fluoride or fluorine containing leaving group, wherein the bimetallic catalyst is supported by an enhanced silica, dehydrated at a temperature of 800° C. or more in one embodiment.
    Type: Grant
    Filed: September 20, 2004
    Date of Patent: September 13, 2005
    Assignee: Univation Technologies, LLC
    Inventors: Chi-I Kuo, G. McCullough Laughlin, Pradeep Pandurang Shirodkar, Fred David Ehrman, Porter Shannon, Robert Lynn Santana, Steven K. Ackerman, Daniel Gerard O'Neil
