Abstract
The present invention pertains to particular HASE rheology modifiers: they are aqueous emulsions whose solids content may reach about 25%, based on acrylic thickeners having an associative monomer functionalized by an oxo alcohol based hydrophobic group. Their method of synthesis, as well as a method for thickening an aqueous formulation containing them, also constitute objectives of the present invention.
