ABSTRACT:
Disclosed are aqueous polyacrylate dispersions having improved rheological and stability characteristics prepared by the emulsion polymerization of acrylic esters, methacrylic esters and mixtures thereof in the absence of a protective colloid, wherein the improvement comprises conducting the polymerization in the presence of, by weight of the total monomer content, from about 0.1 to 2% of at least one substantially completely water-soluble monomer having conjugated unsaturation. The resultant aqueous polyacrylate dispersions are useful in the manufacture of latex paints, binders for nonwoven materials, water-based inks, paper coatings and water-borne adhesives, such as pressure-sensitive adhesives.
