The present invention relates to a composition comprising a mixture of a first and a second hydrophobically modified alkylene oxide polymer, wherein the first hydrophobically modified alkylene oxide polymer is endcapped with at least one first hydrophobic group functionalized with a secondary amine or a salt thereof, or a tertiary amine or a salt thereof; and wherein the second hydrophobically modified alkylene oxide polymer is endcapped with at least one second hydrophobic group, structure I: where R, R, m, and n are as defined herein. The present invention also relates to a method for preparing the composition. The composition of the present invention provides an associative thickener with an excellent balance of as-is viscosity and temperature stability over a wide temperature range.

Hydrophobically modified alkylene oxide polymer mixture

The present invention relates to a compound comprising a hydrophobically modified poly(oxyalkylene-urethane) having a hydrophobic fragment represented by Structure I:  where Ar, Ar; R, m, and n are defined herein. The compound of the present invention provides viscosity stability upon tinting for paints containing a hydrophobically modified poly(oxyalkylene-urethane) rheology modifier, more particularly a HEUR rheology modifier.

Alkylene oxide polymer endcapped with an aryl ether alkoxylate block copolymer

The present invention relates to a composition comprising an aqueous dispersion of acrylic based polymer particles; less than 15 PVC of a pigment; and a hydrophobically modified poly(oxyalkylene-urethane) rheology modifier having a hydrophobic portion represented by Structure I:  Where R, R, R, m an n are defined herein. The composition provides viscosity stability for paint formulations containing a HEUR rheology modifier.

Tint base paint formulation with a poly(oxyalkylene-urethane) associative thickener modified with a hydrophobic oligomer

The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 5.0; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiOparticles; wherein the phosphorus acid functionalized polymer particles have a core-shell morphology wherein the core protuberates from the shell. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.

The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 4.8; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiOparticles. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.

CMP polishing composition for semiconductor devices containing organic polymer particles

The present invention relates to a method and apparatus for determining the dispersion stability of a liquid suspension. The method of the present invention includes exposing the liquid suspension to one or more appropriate wavelengths of light while maintaining insoluble particles in the liquid suspension uniformly suspended, and determining the amount of light scattered by the liquid suspension to assess the dispersion stability of the liquid suspension. The present invention also provides an apparatus for carrying out the method of the present invention. The method and apparatus of the present invention can be used, for example, to determine the effect that an additive has on the dispersion stability of a liquid suspension without having to wait for the liquid suspension to phase separate.
