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.

Abstract: A polymer is disclosed, which includes a structure of Formula 1 or Formula 2. R1 is a C2-18 alkylene group or a C6-18 arylene group, R2 is a C1-18 alkyl group, and R3 is a functional group of Formula 3. Each of X1, X2, X3, X4, X5, and X6, being the same or different, is H or methyl. Each of p, q, and r, being the same or different, is an integer of 1 to 60. R4 is —C2H4—, —C3H6—, Each of m and n, being the same or different, is an integer of 0 to 50, and m+n≠0.
