Abstract

(Meth)acrylate salt polymers are prepared by free-radical polymerization of (meth)acrylate salt with or without other monomers in an aqueous medium by using a supersaturated aqueous solution of (meth)acrylate salt. The resulting highly concentrated reaction mixtures are notable for their high solids content and increased space-time yield.
