Abstract:
The present invention relates to a composition comprising an aqueous solution or dispersion of an associative thickener having a poly(oxyalkylene-urethane) backbone and at least one terminal hydrophobe comprising from 3 to 20 structural units of an acrylate, a methacrylate, a styrene, or a combination thereof. Brookfield, ICI, and KU viscosity profiles can be tuned with greater ease with the composition of the present invention.
