  • Patent number: 10941230
    Abstract: The present invention relates to multi-arm surfactant-system thickening star macromolecules, and methods of preparing and using the same. In one aspect of the invention, a surfactant-system thickening star macromolecule is capable of providing surfactant-compatibility, increase the viscosity of a surfactant-containing system, and/or temperature-stability to an aqueous composition.
    Type: Grant
    Filed: July 1, 2019
    Date of Patent: March 9, 2021
    Assignee: Pilot Polymer Technologies, Inc.
    Inventors: Liang Huang, Yuanxi Liao, Patrick McCarthy
  • Publication number: 20200277422
    Abstract: The present invention relates to multi-arm star macromolecules which are used as thickening agents or rheology modifiers, including use in hydraulic fracturing fluid compositions. In one aspect of the invention, a star macromolecule is capable of thickening via a dual mechanism comprising (1) self-assembly of the hydrophobic polymerized segments of the star macromolecules via hydrophobic interactions or associations, and (2) association, reaction, or combination of the hydroxyl-containing polymerized segments of one or more of the star macromolecules.
    Type: Application
