  • Use of silicon oxide compounds as free-flow agents in the production of solid polyvinyl acetate resins
    Patent number: 8071669
    Abstract: Polyvinyl acetate polymers produced by mass polymerization or suspension polymerization are stabilized against blocking by addition of minor amounts of a silicon oxide compound during the pelletization process of mass polymerized polymers and prior to or during fluidized bed drying in the case of suspension polymerized polymers. The free flowing polymers are suitable for use as chewing gum bases, and for other uses.
    Type: Grant
    Filed: March 2, 2006
    Date of Patent: December 6, 2011
    Assignee: Wacker Chemie AG
    Inventors: Rene Graewe, Marcus Biber, Thomas Wimmer
