Abstract
An aqueous polymer is provided, which is formed by neutralizing a copolymer modified by polyalkylene glycol with ammonia, primary amine, secondary amine, 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.
