| titleOfInvention | Aqueous solution of acrylamide-derived cationic copolymer and its preparation method and use |
| abstract | The present invention relates to a method for preparing an aqueous polymer solution comprising at least one cationic or amphoteric (co)polymer, comprising the steps of: The (co)polymer of at least one nonionic monomer of acrylamide and acrylonitrile is subjected to Hoffman degradation reaction; the obtained polymer aqueous solution of viscosity V1 is subjected to post-treatment; it is characterized in that, the post-treatment comprises the following sequence in sequence Steps: obtaining a polymer aqueous solution containing at least one cationic or amphoteric (co)polymer derived from the Hoffmann degradation reaction; post-processing the polymer aqueous solution; characterized in that, the post-processing sequentially includes The following steps: a. Adjust the pH of the aqueous polymer solution to a value greater than or equal to 5.5; b. Reduce the pH of the aqueous polymer solution to a value between 2 and 5. The present invention also relates to the use of the aqueous polymer solution as a flocculant, a retention aid and/or a drainage agent and a dry strength resistance agent in a papermaking process. |
