Abstract
Acrylate copolymers comprising (a) repeating units derived from at least one acrylic or methacrylic ester and, by weight of the total copolymer, (b) about 0.1 to 3% of repeating units derived from at least one water-soluble monomer possessing conjugated unsaturation and (c) about 0.1 to 3% of repeating units derived from at least one water-soluble allyl monomer; aqueous polyacrylate dispersions comprising such polymers; and a process of preparing the same. Optionally, the copolymers contain other free-radical polymerizable monomers.
