  • Aqueous water barrier coatings
    Patent number: 11821143
    Abstract: Described herein is a multi-phase polymer binder including an aqueous polymer dispersion, an optional hydrophobic emulsion, and an optional surfactant. The polymer binder, when dried, provides a water uptake of less than about 5 g/m2/20 min, a seal strength of at least about 200 Newton/meter (N/m) as measured at 25° C. or at 90° C., and sufficient block resistance to impart no substrate damage.
    Type: Grant
    Filed: November 17, 2020
    Date of Patent: November 21, 2023
    Inventors: Gary A Deeter, Frank Reinhold, Amirpouyan Sardashti, Andrew Seecharan
  • Recyclable Composition for Paper Coating
    Publication number: 20230287627
    Abstract: Disclosed herein is a composition that can provide moisture barrier during packaging. Additionally disclosed herein is a substrate coated with the composition that is recyclable and repulpable. The composition includes at least one ester and at least one styrene acrylic copolymer with a glass transition temperature in the range of from -54° C. to 10° C.

  • Ammonia-based, imide-containing resin cuts of styrene-maleic resins
    Patent number: 11578149
    Abstract: A process of preparing an aqueous solution of a cycloimide-containing polymer includes heating an aqueous solution of a cycloanhydride-containing polymer with a first neutralizing agent at a ratio of cycloanhydride to neutralizing agent of about 1:1 to about 1:1.5 at a temperature and for a time sufficient to form the aqueous solution of the cycloimide-containing polymer having a cycloimide to acid group ratio of about 1:2 to about 1.5:2.
    Type: Grant
