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 TiO2. 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 provides a composition comprising 1) an aqueous dispersion of polymer particles having a core-shell morphology wherein the core protuberates from the shell; wherein the core comprises from 5 to 90 weight percent structural units of a fluoroalkylated monomer, and 2) less than 0.09 weight percent structural units of a phosphorus acid monomer; and wherein the shell comprises from 0.1 to 5 weight percent of itaconic acid or a phosphorus acid monomer, based on the weight of the shell. The present invention addresses a need in the art by providing a way of selectively concentrating fluoroalkyl functionality into polymer particles with acorn morphology, thereby providing an improvement in dirt pick-up resistance of the subsequent coating.

摘要： The present invention relates to a process for preparing an aqueous dispersion of a vinyl acetate polymer comprising the step of polymerizing vinyl acetate under emulsion polymerization conditions in the presence of a chain transfer agent which is a hypophosphite salt or X—R1—SH, where R1 is a C1-C4 alkyl group and X is sulfonate, hydroxyl, sulfate, phosphate, phosphonate, carboxylic acid or a salt thereof, or C1-C3-alkyl carboxylate. The process provides a way of lowering the viscosity of the vinyl acetate polymer at a given solids content.
