  • Patent number: 9777100
    Abstract: Polymer latex binders useful for preparing coating compositions containing low levels of, or which are substantially free of, volatile organic compounds (VOCs) such as volatile freeze-thaw additives are prepared by multistage emulsion polymerization, wherein one stage provides a copolymer having a relatively high glass transition temperature and containing an oxyalkylene-containing (meth)acrylate comonomer.
    Type: Grant
    Filed: December 2, 2016
    Date of Patent: October 3, 2017
    Assignee: Arkema Inc.
    Inventors: Wenjun Wu, Jihui Guo, Jeffrey A. Schneider
  • Patent number: 9745492
    Abstract: The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 4.8; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiO2 particles. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.
    Type: Grant

    Date of Patent: August 29, 2017
    Assignee: Rohm and Haas Company
    Inventors: James C. Bohling, Arnold S. Brownell, Jihui Guo, Kevin J. Henderson, Ericka Lynn Killian, John J. Rabasco, Daniel A. Saucy, Jordan Stracke
  • Patent number: 9745478
    Abstract: The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 5.0; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiO2 particles; wherein the phosphorus acid functionalized polymer particles have a core-shell morphology wherein the core protuberates from the shell. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.
