摘要： An aqueous silica dispersion containing silica particles dispersed in an aqueous medium is provided. The surfaces of the silica particles are treated with reacted aminosilane compound. The aqueous silica dispersion also contains anionic polymeric dispersing agent. The dispersion of the silica particles into an aqueous medium containing both anionic polymeric dispersing agent and aminosilane compound allows the preparation of aqueous silica dispersions at higher solids and/or low viscosities than aqueous silica dispersions that are prepared without either the anionic polymeric dispersing agent or the aminosilane compound. The aqueous silica dispersion is combinable with aqueous emulsion polymers to modify the physical or appearance properties of articles formed from the emulsion polymer.

摘要： An aqueous polymeric composition containing select polymeric nanoparticles is provided. The select polymeric nanoparticles contain as polymerized units at least one multiethylenically unsaturated monomer and at least one water soluble monomer; and have a mean diameter in the range of from 1 to 50 nanometers. Also provided are aqueous polymeric compositions that further contain second particles such as pigment particles or second polymer particles. The aqueous polymeric composition is useful for preparing coatings having at least one improved property compared to a coating absent the select polymeric nanoparticles. Further, the aqueous polymeric composition is useful for treating wood. A coating prepared from the aqueous polymeric composition is also provided.
