Abstract
New associative thickening agents belonging to the category of HASEs (Hydrophobically modified Alkali-Soluble Emulsions). These products contain an original associative monomer with a base of alkylcyclohexanol akoxylates. Their thickening power is greater than the HASE associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyls phenols, matching current market demand.
