  • AQUEOUS POLYMER, DISPERSION, AND AQUEOUS PAINT
    Publication number: 20210070925
    Abstract: An aqueous polymer is formed by neutralizing a copolymer modified by polyalkylene glycol with ammonia, primary amine, secondary amine, inorganic base, or a combination thereof, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The aqueous polymer can be mixed and dispersed with water and pigment powder to form a dispersion. The dispersion can be mixed with binder to form an aqueous paint.
    Type: Application
    Filed: September 3, 2020
