  • Method for precisely controlling the dissolution rate of high molecular weight water-soluble vinyl polymers
    Patent number: 4252706
    Abstract: The dissolution rate of water-soluble polymers in water can be precisely controlled. This is accomplished by inverting a water-in-oil emulsion containing the water-soluble vinyl polymer into water which contains at the time of inversion an exact amount of an emulsifier system having an HLB number which has been predetermined to produce a specific solubility rate for the water-soluble vinyl polymer.
    Type: Grant

    Date of Patent: February 24, 1981
    Assignee: Nalco Chemical Company
    Inventors: Kenneth G. Phillips, Alvin J. Frisque
  • Clay-polymer concentrates for beneficiating clays
    Patent number: 4128528
    Abstract: A method is disclosed for the preparation of concentrated, homogeneous, free flowing clay-polymer powders which upon addition to an aqueous solution may be inverted so as to produce a beneficiated clay.
    Type: Grant

  • Oil base paints containing water-soluble polymers
    Patent number: 4075144
    Abstract: Disclosed are oil base paints which contain uniformly dispersed therethroughout 2 to less than 50% by weight of a water-in-oil emulsion which emulsion contains at least 2% by weight of particles ranging in size from 5 millimicrons to 5 millimeters of a water-soluble vinyl addition polymer.

    Inventor: Alvin J. Frisque
  • Method of sealing leaks in metal oil storage containers
    Patent number: 4010231
    Abstract: This invention relates to sealing small leaks in oil containers such as tankers, underground storage tanks, and the like, by plugging the orifice of the leak utilizing water-soluble polymers which have been dispersed in a water-in-oil emulsion wherein the oil is the continuous phase.The active sealant consists of small densely packed spheres of the water-soluble polymers which have an effective size of about 0.5-500 microns. The dosage on an oil-wet surface is about 3-15 percent based on the weight of the oil present and may alternatively be measured as about 10-1000 ppm of polymer spheres applied to the orifice.

  • Windshield washer fluids containing from 10-1000 ppm of acrylamide polymer to reduce wear of wiper blades and reduce windage losses of fluid
    Patent number: 3989633
    Abstract: Windshield washer fluids of the type comprising a major portion of water, one or more water-soluble alcohols which are predominantly monohydric alcohols capable of depressing the freezing point of water and a surfactant can be improved in their operational efficiency by adding thereto from between 10-1,000 ppm of an acrylamide polymer having a molecular weight of at least 10,000.
