Embodiment 1
[0090] 1. Add 25.025g of acrylamide (mass content 91%) into an insulated polymerization reaction bottle (ie, a polymerization bottle), add 72.5g of deionized water to dissolve and make an aqueous solution, and then add sodium hydroxide to adjust the pH to 7.2;
[0091]2. Add 1.1g functional monomer X (mass content 4%), 1.375g functional monomer Y1 (mass content 5%), emulsifier 0.25g, 1% EDTA-2Na aqueous solution 0.3g, urea 1.375g, amidine 55.0 mg of thiourea, fully stirred to form stable micelles;
[0092] 3. Control the temperature of the aqueous solution at 25°C. After 30 minutes of blowing nitrogen to drive oxygen, add 1.4g of 0.2% potassium persulfate aqueous solution and 1.4g of 0.1% sodium bisulfite aqueous solution to initiate the reaction, and continue to blow nitrogen for five minutes. Stop, polymerize for 10 hours after sealing;
[0093] 4. Take out the rubber block, add 0.52g granulated alkali after granulation, mix evenly, and then carry out hydrolysis at 80°C for...
