| titleOfInvention | Production procedure of stabilized polyacrylamides |
| abstract | A process for preparing a composition comprising at least one water-soluble acrylamide polymer and at least one St stabilizer, which comprises the following steps: a) providing an aqueous MS monomer solution comprising 20% to 45% by weight, based at the total amount of all components of the aqueous MS monomer solution, of at least one ethylenically unsaturated monomer, at least one monomer that is (meth) acrylamide, at least one initiator I for free radical polymerization and at least one solvent So it comprises at least 50% by weight, based on the total solvent So, of water; b) polymerize the aqueous MS monomer solution to obtain the acrylamide polymer P in the form of a polymer gel; c) treating the polymer gel having a water content in the range of 50% to 80% by weight, based on the entire polymer gel, with an aqueous solution SS comprising at least one St stabilizer, in which In case St, the stabilizer is at least one mercapto compound that is selected from the group consisting of 2-mercaptobenzothiazole and salts thereof, d) optionally drying the polymer gel of step c. |
