Abstract: Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to be used in contact with skin.

Abstract: The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, traces of brushes and filling-knives.

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.
