Abstract
A HASE-type rheology modifier containing an associative monomer which is functionalised by a hydrophobic group of an oxo alcohol base is provided. A method to prepare the HASE rheology modifier and its use in a method to thicken and create a Newtonian rheological profile in an aqueous formulation such as a water based paint is also provided.
