Abstract
The present invention concerns new associative thickening agents belonging to the category of HEURs (Hydrophobically modified Ethylene oxide URethane). These products contain an original associative monomer with a base of alkyl cyclohexanol alkoxylates. Their thickening power is equal to or greater than that procured by HEUR associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyl phenols, matching current market demand.
