  • Production of high haze films using metallocene-based catalyst systems in cyclohexene
    Patent number: 10131725
    Abstract: Methods for preparing metallocene-based catalyst systems containing an activator-support are disclosed. These methods are directed to contacting an activator-support, an organoaluminum compound, and a mixture containing a metallocene compound and cyclohexene or a mixture of cyclohexane and 1-hexene, resulting in catalyst systems with increased catalytic activity for the polymerization of olefins. The olefin polymers can be used to produce film products with high haze values.
    Type: Grant
    Filed: November 9, 2017
    Date of Patent: November 20, 2018
    Assignee: Chevron Phillips Chemical Company LP
    Inventors: Kensha Marie Clark, Qing Yang, Gary L. Glass
