  • Polyether polymerization process
    Patent number: 12152104
    Abstract: Polyethers are prepared by polymerizing an alkylene oxide in the presence of a double metal cyanide catalyst complex and certain M5 metal or semi-metal compounds. The double metal cyanide catalyst complex contains 0.5 to 2 weight percent potassium. The ability of this catalyst system to tolerate such high amounts of potassium permits the catalyst preparation procedure to be simplified and less expensive.
    Type: Grant
    Filed: February 17, 2020
    Date of Patent: November 26, 2024
    Assignee: Dow Global Technologies LLC
    Inventors: Haifeng Shi, Mrunmayi Kumbhalkar, Jason S. Fisk, Curtis M. Whaley, David A. Babb, Brian J. Murdoch
