Disclosed are novel tri-substituted aromatic-alkoxylated monomers, polymers made with the novel tri-substituted aromatic-alkoxylated monomers, pH responsive polymers made with the novel tri-substituted aromatic-alkoxylated monomers, and related methods. Also disclosed is an aqueous coating composition including at least one latex polymer derived from at least one monomer copolymerized or blended with alkali swellable acrylate copolymer. Also provided is a method of preparing an aqueous coating composition such as a latex paint including the above components.

Tri-substituted aromatic-containing monomers, copolymers and methods for use

Disclosed are novel tri-substituted aromatic-alkoxylated surface active compounds. Also provided is a method of preparing an aqueous coating composition such as a latex paint including the above components.

Tri-substituted aromatic-containing additives and surfactants and methods for use

The present invention relates to a pre-paint composite comprising an aqueous slurry of TiOparticles and a polymeric binder, wherein from 35 to 90 weight percent of the polymeric binder is attached to the TiOparticles, 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.

Freeze-thaw stable paint formulation

A process for encapsulating TiOparticles by polymerizing sodium styrene sulfonate with a redox initiator system; then polymerizing a first monomer mixture comprising at least 60 wt % acrylic monomers; then polymerizing a second monomer mixture comprising at least 40 wt % vinyl ester monomers.

Method of making polymer encapsulated titanium dioxide particles

The present invention relates to a pre-paint composite comprising an aqueous slurry of TiOparticles and attached and unattached polymeric binder, and a sufficient amount of a secondary alcohol ethoxylate of the formula CHO(CHCHO)H to give 35 to 90 weight percent attachment of polymeric binder to the TiOparticles, based on the weight of total polymeric binder in the pre-paint composite, where x is from 15 to 50; and the O(CHCHO)H group is bonded to a CH group on the CHchain. The present invention also relates to a coatings composition containing the composite as well as a process for preparing the pre-paint composite and the coatings composition.
