Abstract
Disclosed are polymer blends of polyesters or polyesteramides and a polymer containing an acrylamide sulfonate monomer. The blends are preferably prepared by polymerizing monomers in the presence of the polyester or polyesteramide. The blends impart superior freeze-thaw stability to aqueous compositions such as inks.
