Abstract: The invention relates to a copolymer obtained by polymerisation reaction of at least three comonomers: a first anionic monomer, a second monomer comprising an olefin unsaturation, and a third monomer comprising a hydrophobic group. The invention likewise relates to the use of said copolymer as a thickening agent, in particular in aqueous suspensions of mineral particles with high solids content. The copolymer according to the invention makes it possible to improve the compromise between viscosity with high shear gradient and viscosity with low shear gradient, while also improving water retention inside the suspension.

Abstract: The invention relates to a rheology-modifying urethane compound. The compound comprising urethane functions of the invention can be prepared according to a method in several steps which use different compounds comprising isocyanate functions. For the preparation of the urethane compound according to the invention, a monoisocyanate compound, in particular a monoisocyanate compound resulting from the separate condensation of an asymmetric diisocyanate compound with a reactive compound, is reacted with an alkylene glycol compound in the presence of a polyisocyanate compound. The invention also provides coating compositions comprising mineral particles and a urethane compound according to the invention.
