1/1 abstract of a thickener, acidic formulation, uses of an acidic formulation, an alkaline formulation, and a thickener, and, an acidic formulation Alkaline The present invention relates to a thickener obtainable according to a method, characterized in that a polymer is obtained by an inverse emulsion polymerization of a) at least one water-soluble ethylenically unsaturated monomer comprising at least one anionic monomer and/or at least one non-ionic monomer, b) at least one associative monomer ethylenically unsaturated, c) optionally at least one crosslinker, d) optionally at least one chain transfer agent. the temperature is kept constant during the inverse emulsion polymerization and is at least 40°C, preferably between 50 to 90°C, and the activator is added after the polymerization in reverse emulsion in order to obtain the thickener. |
