Abstract
The invention relates to methods of preparing aqueous polymeric dispersions which contain a water-dispersible polyurethane, a polymer prepared from an ethylenically unsaturated monomer and at least one additional polymer which is capable of enhancing certain properties of products which utilize the aqueous dispersions of the present invention, wherein the ethylenically unsaturated monomer is polymerized in the presence of the water-dispersible polyurethane dispersion and the additional polymer and in the absence of a surfactant and an organic solvent, to aqueous compositions containing the aqueous polymeric dispersions and to articles of manufacture prepared from the aqueous compositions containing the aqueous polymeric dispersions.
