  • Methods of using pressure-sensitive adhesives
    Patent number: 5435879
    Abstract: Normally tacky, pressure sensitive adhesive compositions comprise one or more polymers containing pendant functional groups attached to a polymer backbone and having the formula: ##STR1## in which R.sub.
    Type: Grant
    Filed: November 7, 1990
    Date of Patent: July 25, 1995
    Assignee: Rohm and Haas Company
    Inventors: Gaylen M. Knutson, Paul J. Steinwand, Joseph J. Wilczynski, Lonnie T. Spada
  • Latex-paints
    Patent number: 5219917
    Abstract: The ICI viscosity of a paint is improved by incorporating into the paint a binder that comprises a film former and polymeric composition. The polymeric composition comprises about 30 to about 50 weight percent of a substantially non-self-polymerizable monomer and about 50 to about 70 weight percent of a copolymerizable monomer having a water-soluble homopolymer. The polymeric composition and film former are substantially inseparable by chromatographic means.
    Type: Grant
    Filed: July 14, 1992
    Date of Patent: June 15, 1993
    Assignee: Rohm and Haas Company
    Inventors: David M. Ingle, Gaylen M. Knutson

    Inventors: David M. Ingle, Gaylen M. Knutson
  • Latex paints
    Patent number: 5124393
    Abstract: The ICI viscosity of a paint is improved by incorporating into the paint a binder that comprises, in part, a supplemental polymer. The supplemental polymer comprises about 20 to about 60 weight percent of a substantially non-self-polymerizable monomer and about 40 to about 80 weight percent of a copolymerizable monomer having a water-soluble homopolymer. The supplemental polymer and binder are substantially inseparable by chromatographic means.
    Type: Grant
    Filed: April 30, 1990
    Date of Patent: June 23, 1992
    Assignee: Union Oil Company of California
    Inventors: David M. Ingle, Gaylen M. Knutson
  • Emulsion polymers and paint formulated therewith
    Patent number: 5118749
    Abstract: ICI viscosity of a paint is improved by incorporating into the paint an acrylic polymer emulsion or latex made with the use of a water soluble chain transfer agent, preferably one that comprises both sulfur functionality and hydroxyl functionality. A preferred chain transfer agent is monothioglycerol.
    Type: Grant
    Filed: August 31, 1989
    Date of Patent: June 2, 1992
    Assignee: Union Oil Company of California
    Inventor: Gaylen M. Knutson
  • Polymer systems and methods for their production
    Patent number: 5116895
    Abstract: Polyamines having at least two amine groups are incorporated into a polymer system comprising an anionic surfactant and a polymer having at least one anionic pendant group. The resulting polymer system typically exhibits at least one improved physical property.
