| titleOfInvention | Process for preparing stabilized polyacrylamide compositions |
| abstract | The present application relates to a process for preparing a composition comprising at least one acrylamide polymer P and at least one stabilizer St for preventing degradation of the polymer by molecular oxygen, wherein the acrylamide polymer P is obtained in the form of a polymer gel and the acrylamide polymer gel having a water content of at least 30 wt. -%, based on the total polymer gel, is treated with an aqueous solution SS comprising from 0.1 to 50 wt. -%, based on the total aqueous solution SS, of the at least one stabilizer St. |
