Abstract: A polymer is formed by capping a copolymer-graft-polylactone with an alcohol, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The polymer can be mixed with an organic solvent and pigment powder to form a dispersion. The dispersion can be mixed with a binder to form a paint.

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.
