NONIONIC ASSOCIATIVE THICKENERS CONTAINING CYCLOHEXYLOL ALKYLS, FORMULATIONS CONTAINING SAME AND USES THEREOF

摘要

The invention relates to novel associative thickeners of the hydrophobically modified ethylene oxide urethane (HEUR) type, of which the hydrophobic monomer is based on cyclohexylol alkyls. It is these novel polyurethanes that allow the liberal thickening of an aqueous formulation at a medium shear gradient, while limiting the increase in the viscosity at a low shear gradient. The invention also relates to compositions containing said thickeners and to the uses thereof in different formulations such as water-based paints.
