Abstract
The present invention concerns new associative thickeners of the HEUR type (Hydrophobically modified Ethylene oxide URethane) whose hydrophobic monomer is based on alkyl cyclohexylols. These are new polyurethanes that significantly thicken an aqueous formulation with a low, medium and high shear gradient. The invention also concerns the compositions containing them and their uses in different formulations such as aqueous paints.
