<p>Disclosed are aqueous polyacrylate dispersions, i.e., aqueous latex dispersions of acrylate polymers, having improved rheological and stability characteristics prepared by polymerization of acrylic esters, methacrylic esters and mixtures thereof in the presence of, by weight of the total monomer content, a) from about 0.05 to about 3.5% of at least one surface active protective colloid, and b) from about 0.01 to 1% of an azo initiator. 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.</p> |
