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 present invention concerns weakly anionic polymers including their use in paper coatings, especially those intended for paper for inkjet printing. These additives provide the sought thickening function, while improving water retention very appreciably. The invention also concerns a method of manufacture of such coatings, together with the coatings obtained in this manner.

Abstract: A method for deinking recycled paper, including a pulping step, and then a flotation step, which includes introduction of at least one dispersant of the polyacrylate type, representing from 0.05 to 3.5 wt % of the mineral fillers of the recycled paper. A specific dispersant is used during the flotation step of the method for deinking recycled paper.
