Embodiment 1
[0024] Take 8.0g of N-vinylformamide and 2.0g of diallyldimethylammonium chloride and add them to 40g of deionized water, stir evenly to form a monomer solution with a mass fraction of 20%, and then add azo Diisobutylamidine hydrochloride. After thorough stirring, the solution was transferred to a flask equipped with a condenser, and the polymerization reaction was carried out under the protection of nitrogen. After the polymerization reaction is finished, hydrochloric acid solution is added to the reaction system, and the hydrolysis reaction is carried out under the protection of nitrogen. The solution obtained by the hydrolysis reaction was added into ethanol, and the precipitated product was dissolved in deionized water and stirred thoroughly. Add strong basic anion exchange resin into the solution, carry out suction filtration treatment after fully stirring, and add ammonium carbonate to the solution obtained by suction filtration. Dialysis treatment is carried out after...
