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 presence of, by weight of the total monomer content, (a) from about 0.1 to 5% of at least one water-soluble amino alcohol compound and (b) from about 0.05 to about 5% of at least one protective colloid. 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.
