add N,N-dimethylaminoethyl α-methacrylate into the reaction kettle, add deionized water to dissolve, then adjust the pH value to about 3.5 with phosphoric acid. Add acrylamide and acrylic acid aqueous solution (the molar ratio of the three monomers is 1:1: 1). Ammonium persulfate equivalent to about 0.4% of the total monomer is added as initiator and 4-carboxybutanol is used as chain transfer agent. The product was obtained by stirring at 60 ℃ for 3 h.
