Abstract:
The present application relates to a process for producing a composition comprising at least one acrylamide polymer P and at least one stabilizer St, wherein the acrylamide polymer P is obtained in the form of a polymer gel, and the acrylamide polymer gel having a water content in the range from 50% to 80% by weight, based on the overall polymer gel, is treated with an aqueous solution SS comprising at least one stabilizer St selected from the group consisting of sulfur compounds, N-oxides, organic nitroso compounds, aromatic hydroxyl compounds and ketones.
