  • Multi-modal emulsions of water-soluble polymers
    Patent number: 4619967
    Abstract: Multi-modal emulsions comprise a continuous oil phase and a discontinuous aqueous phase having two or more droplet size distributions and comprising a water-soluble polymer. Such emulsions are prepared by subjecting portions of the emulsion to varying rates of shear during emulsion formation. The multi-modal emulsions can have high polymer solids, reduced oil content, low bulk viscosity and high stability.
    Type: Grant
    Filed: November 2, 1984
    Date of Patent: October 28, 1986
    Assignee: The Dow Chemical Company
