    Abstract: 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.

    Abstract: The present invention relates to a stable aqueous dispersion of multiphase amphoteric polymer particles comprising a crosslinked polymer phase comprising structural units of a phosphorus acid monomer, a carboxylic acid monomer, a multiethylenically unsaturated monomer, and an ethylenically unsaturated nonionic monomer; and a second polymer phase comprising a carboxylic acid monomer and an ethylenically unsaturated nonionic monomer. The present invention also relates to composites of the particles and pigment particles such as TiO2. The composition is useful for preparing dried coatings with improved hiding.
