Abstract:
The present invention relates to a stable aqueous dispersion of polymer particles with structural units of a) a phosphorus acid monomer or a salt thereof; b) a carboxylic acid monomer or a sulfur acid monomer or a salt thereof or a combination thereof; c) a multiethylenically unsaturated monomer; and d) an acrylate monomer, wherein the polymer particles have a solids content in the range of 30 to 50 percent and a particle size of from 40 nm and 100 nm.
Abstract:
The present invention relates to an in situ method for preparing a bimorphological aqueous dispersion of first polymer particles with protuberating phosphorus acid cores and second polymer particles without protuberating cores. The method provides a more efficient way of making compositions for pigmented coating formulations.
Abstract:
The present invention relates to a pre-paint composite comprising an aqueous slurry of TiO2 particles and a polymeric binder, wherein from 35 to 90 weight percent of the polymeric binder is attached to the TiO2 particles, based on the weight of polymeric binder in the pre-paint composite. The pre-composite of the present invention is useful in paint compositions, particularly those that require freeze-thaw stability
Abstract:
The present invention relates to a composition comprising a bimorphological aqueous dispersion of first and second polymer particles, wherein the first polymer particles comprise a shell and a phosphorus acid functionalized protuberating core, and the second polymer particles do not comprise a protuberating core. The composition is useful for pigmented coatings formulations.

Abstract:
The present invention relates to a process comprising contacting a stable aqueous dispersion of pre-formed polymer particles with a monomer emulsion under emulsion polymerization conditions to form a stable aqueous dispersion of pre-formed particles protuberating from polymer particles arising from the polymerization of the monomer emulsion; these multistage polymer particles show exceptional compatibility with pigment particles. In another aspect, the present invention is a composition relating to the pre-formed particles.
