  • Patent number: 11718697
    Abstract: Disclosed herein is an aqueous latex composition comprising a substantially acrylic core-shell latex, wherein a water-retaining monomer is copolymerized to the shell. The Tg of the core ranges from about 0° C. to about 12° C., and the Tg of the shell ranges from about 13° C. to about 40° C. The mean volume average particle size of the latex ranges from about 125 nm to about 200 nm. The core-shell latex comprises at least one acrylic monomer having a solubility that ranges about 10 g/L to about 30 g/L at 30° C., and this at least one acrylic monomer is present in the shell polymer in an amount greater than about 50 wt. % of all monomers in the shell. Preferably, the at least one acrylic monomer is methyl methacrylate.

  • Patent number: 11639406
    Abstract: Disclosed herein is an aqueous latex composition comprising latex particles dispersed in an aqueous solution, wherein the latex particles are polymerized from at least one acrylic monomer in a substantially solvent-free, waterborne environment, and a 2-oxazoline compound is incorporated onto the latex particles. The 2-oxazoline compound has the following structure: The 2-oxazoline compound is present from about 1 wt. % to about 5 wt. %. The 2-oxazoline may be grafted onto the latex particles. R1 moiety may be free of an acyclic organic radical having addition polymerizable unsaturation moiety. The aqueous latex composition may also comprises an acid monomer.

  • Publication number: 20220135808
    Abstract: Solutions to the problems of scuffing and chipping of the paint films in high traffic areas and in tight spaces, such as dressing rooms in department stores, where multiple scrapings of the wall paints are created by consumers, clothes hangers, shoes, etc., and hallways and conference rooms in office and other commercial buildings are disclosed. Wax seeded latex polymers admixed with an added wax in architectural compositions and optionally with polyurethane resin are utilized to create paint films that are resistant to scuffing and chipping.
