摘要： The present invention relates to the use, for the manufacture of a hydroalcoholic composition comprising 50% to 80% by weight of at least one alcohol and at least 10% by weight of an aqueous phase, of a branched or crosslinked polymer obtained by polymerization of an aqueous solution of one or more monomers in a water-in-oil inverse emulsion, at least one of the monomers used being an acrylic monomer and one or more of the monomers used being a monomer bearing at least one weak acid function, the molar percentage of monomers bearing at least one weak acid function relative to all the monomers used being at least 30%, and wherein: i) the polymerization is carried out with a concentration of all the monomers in aqueous solution belonging to the range from 1.3 mmol to 3.6 mmol per gram of aqueous solution, ii) during the polymerization, at most 20 mol % of the acid functions present on the monomers having at least one acid function are found in neutralized form.

摘要： The present invention relates to a method for inerting clays in hydraulic compositions intended for construction purposes, said method comprising a step of adding to the hydraulic composition or to one of its constituents at least one clay inerting agent, characterised in that the clay inerting agent is a water-soluble polymer comprising acrylamide, and/or vinylamine, and/or vinylformamide monomer units, and optionally monomer units of a different chemical nature from the abovementioned chemical natures, and characterised in that its weight average molecular weight is between Mw L and Mw H.
