Abstract: The present invention is a composition comprising a stable aqueous dispersion of polymer particles comprising structural units of a nonionic monoethylenically unsaturated monomer; 2-(methacryloyloxy)ethyl phosphonic acid (MEP) or a salt thereof; and a sulfur acid monomer or carboxylic acid monomer or a combination thereof or a salt thereof, as well as a composite comprising the polymer particles adsorbed to the surface of a pigment particle such as TiO2. The composition and composite are prepared using the phosphorus acid monomer MEP, which can be prepared in high purity with low residual non-polymerizable phosphorus acid, thereby reducing the load of neutralizing agent required to achieve the targeted pH as compared with phophoethyl methacrylate (PEM).

Abstract: 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.

Abstract: The present invention is a multilayered composite comprising porous metal oxide particles that are covalently bonded by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer. This first polymer is in turn covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. The multilayered composites can be prepared by contacting porous inorganic-oxide particles with a sufficient amount of OH-reactive crosslinking agent to form metal oxide particles imbibed with the crosslinking agent, and then contacting the inorganic-oxide particles with a solution of polyhydroxyl-functionalized polymer under reactive conditions.

Abstract: The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with a polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof and a dialkyldihydroxysilane or a salt thereof. The composition of the present invention provides hydrophobicity to pigment particles, thereby imparting water resistance, and allows for high loadings of pigment in water without increased viscosity.

Abstract: The present invention relates to composition comprising an aqueous dispersion of microspheres and a class of a nonionic polyalkylene oxide of a distyryl or tristyryl phenol or an anionic polyalkylene oxide salt of a distyryl or tristyryl phenol and a process for preparing the composition. The microspheres have an average particle size in the range of from 1 μm to 25 μm, as well as a low coefficient of variation and low gel concentration; the composition is useful in coatings applications, especially where a matte finish is desired.
