  • Process for producing a stabilized latex emulsion adhesive
    Patent number: 5081166
    Abstract: An improved process for producing stabilized core-shell latex emulsion adhesives is disclosed. In a process which comprises preparing a hydrophilic polymer and thereafter contacting the hydrophilic polymer with a hydrophobic monomer for producing an inverted core-shell latex emulsion, the improvement comprises the additional step of adjusting the pH of the inverted core-shell latex emulsion for dissolving the hydrophilic polymer, thereby to produce a stabilized latex emulsion adhesive.
    Type: Grant
    Filed: November 2, 1990
    Date of Patent: January 14, 1992
    Assignee: S. C. Johnson & Son, Inc.
    Inventors: Richard A. Kiehlbauch, Vince S. Volk, Lee W. Morgan, Richard J. Esser, Dennis P. Jensen
  • Stable emulsion polymers and methods of preparing same
    Patent number: 4894397
    Abstract: An improved process for pruducing stabilized, core-shell latex emulsions is disclosed. In a process which comprises preparing a hydrophilic polymer and contacting the hydrophilic polymer with a hydrophobic monomer for producing an inverted core-shell latex emulsion, the improvement comprises the additional step of adjusting the pH of the inverted core-shell latex emulsion to dissolve the hydrophilic polymer, thereby to produce a stabilized, core-shell latex emulsion.
    Type: Grant
    Filed: April 21, 1988
    Date of Patent: January 16, 1990
    Assignee: S. C. Johnson & Son, Inc.
    Inventors: Lee W. Morgan, Richard J. Esser, Dennis P. Jensen
  • Emulsion copolymerization process
    Patent number: 4628071
    Abstract: An emulsion polymer of a water insoluble vinylic monomer and an acrylic monomer is formed by precharging a portion of the acrylic monomer and thereafter adding a comonomer charge corresponding to the final desired composition of the vinylic monomer and acrylic monomer at an addition rate generally corresponding to the steady state monomers concentration. A high non-volatiles content is maintained to inhibit the acrylic monomer from partitioning into the aqueous phase.

  • Bulk polymerization process for preparing high solids and uniform copolymers
    Patent number: 4546160
    Abstract: A process to continuously bulk polymerize acrylic monomers to prepare low molecular weight, uniform, polymers employs minor amounts of initiator and, optionally solvents, at short residence times and moderate reaction temperatures to provide high yields of a product suitable for high solids applications.

  • Cleaner-polish for fiberglass and ceramic surfaces
    Patent number: 4347151
    Abstract: A cleaner-polish for kitchen and bathroom surfaces comprising from about 0.3 to 8% of an anionic or nonionic surfactant which produces an oil-in-water emulsion, from about 0 to 18% of an abrasive, from about 5 to 40% of an isoparaffinic hydrocarbon having a kauri-butanol value of from 27 to 29, from about 1 to 8% by weight of a polymer having a number average molecular weight greater than 3,000 and soluble in said hydrocarbon and the balance water.

  • Emulsion coating composition containing silicone and acrylic polymer
    Patent number: 4347333
    Abstract: Oil-in-water and water-in-oil emulsion hard surface coating compositions containing a solvent within a specified solubility parameter, silicone fluids, an acrylic polymer soluble in the solvent, surfactants, water and optionally waxes and abrasives. The compositions have excellent detergent resistance, have good gloss and buff properties.
