    摘要: The present invention is a composition comprising a) a stable aqueous dispersion of polymer particles functionalized with structural units of a phosphorus acid monomer or a salt thereof and; b) a water-soluble polymer functionalized with structural units of a sulfonic acid monomer or a salt thereof as well as a method comprising mixing the stable aqueous dispersion of the phosphorus acid functionalized polymer particles with the sulfonic acid functionalized polymer, and TiO 2 . The composition of the present invention is useful as a coatings formulation that provides improved hiding over phosphorus acid functionalized binders that do not include the water-soluble polymer. Alternatively, the same hiding benefit is seen at lower phosphorus acid concentration when the sulfonic acid functionalized polymer is present.

    摘要: The present invention is a process for preparing an aqueous solution of a hydrophobically modified alkylene oxide poly(urethane-urea-allophanate) thickener by contacting isocyanate reactive groups with a stoichiometric excess of a diisocyanate, followed by reaction with water. The thickener surprisingly shows a maintenance or improvement in hiding in paint formulations while maintaining other critical rheological properties.
