Abstract: Methods for preparing hydrophobically modified alkylene oxide urethane branched polymers. In an embodiment, the order of addition of reactants affects the properties of the resultant product urethane. In an embodiment, the time at which one or more reactants are added affects the properties of the resultant product urethane.

Abstract: An ICI viscosity regulating composition including linked segments of: (a) a polyhydroxy segment having 4 to 6 reactive hydroxyl groups; derived from a compound selected from: an acyclic or cyclic polyhydric alcohol having 4 to 6 carbon atoms, an alkoxylated acyclic polyhydric alcohol, an alkoxylated cyclic polyhydric alcohol and a poly(hydroxyethyl)polyethyleneamine; and combinations thereof; (b) aliphatic or aromatic linking segments, each linking segment having at least two linking groups independently selected from the group of: urethane, urea, ether, ester, amine, an aminoplast segment, a linking group which is the residue from reaction of an epihalohydrin and a hydroxyl group, and mixtures thereof; (c) polyoxyalkylene segments; (d) and aliphatic or aromatic end segments, each end segment having 6 to 22 carbon atoms and a linking group reactive moiety, wherein the mole ratio of the polyoxyalkylene segment to the polyhydroxy segment is at least 4:1 and the mole ratio of the aliphatic or aromatic end segmen

Abstract: A system and method to improve the color acceptance of color viscosity stabilized latex paints. The system includes a base paint, 0.05 wt % to 5 wt % of a color viscosity stabilizing compound; a colorant compound, and; a sufficient amount of a hydrophobically modified alkali swellable emulsion (“HASE”) thickener to improve the color acceptance properties of the paint, which amount is typically 0.02 wt % to 0.5 wt % of the paint, and optionally, 0.1 wt % to 5 wt % of a condensation polymer associative thickener including polyether polyurethanes, polyether polyols, polyether polyacetals, and polyether aminoplasts. The system demonstrates improved color acceptance as measured by rub-ups and ?E values.
