Embodiment 1
[0060] The preparation of embodiment 1, cationic polymer MCF-1
[0061] The reaction equation is as follows:
[0062]
[0063] 22g acrylamide (Sinopharm Chemical Reagent Co., Ltd.) (C 3 h 5 NO, 71.08g / mol) and 18g tris(dimethylamino)methyl-3-butenyl ether hydrochloride monomer are dissolved in 50mL deionized water to obtain monomer aqueous solution, and then the monomer aqueous solution is added to containing 8.25gSpan -80 (Jiangsu Haian Petrochemical Factory) and 6.75gTween-80 (Jiangsu Haian Petrochemical Factory) in 135g cyclohexane (Sinopharm Group Chemical Reagent Co., Ltd.), emulsified under a high-shear homogeneous emulsifier for 15min, Get lotion. Add the above-mentioned emulsion to a 500mL four-necked bottle equipped with a stirrer, a thermometer, a dropping funnel, and a ventilation tube, and after stirring for 20 minutes, add 0.06 g of potassium persulfate (Sinopharm Chemical Reagent Co., Ltd.) and 0.02 g of sodium bisulfite (Sinopharm Chemical Reagent Co., Lt...
Embodiment 2
[0068] The preparation of embodiment 2, cationic polymer MCF-2
[0069] 16g of acrylamide and 24g of tris(dimethylamino)methyl-3-butenyl ether hydrochloride monomer were dissolved in 50mL of deionized water to obtain a monomer aqueous solution, and then the monomer aqueous solution was added to 8.25g of Span-80 and 6.75 g of Tween-80 was emulsified in 135 g of cyclohexane for 10 min under a high-shear homogeneous emulsifier to obtain an emulsion. Add the above-mentioned emulsion into a 500mL four-necked bottle equipped with a stirrer, a thermometer, a dropping funnel, and a ventilation tube, and after stirring for 20 minutes with nitrogen and deoxygenation, add dropwise an aqueous solution containing 0.06g of potassium persulfate and 0.02g of sodium bisulfite 10 mL, control the reaction temperature to 45°C, and stop the reaction after 4 hours of constant temperature. Add acetone to precipitate, filter under reduced pressure, wash with acetone twice, and filter to obtain a pow...
Embodiment 3
[0074] The preparation of embodiment 3, cationic polymer MCF-3
[0075] 11g of acrylamide and 29g of tris(dimethylamino)methyl-3-butenyl ether hydrochloride monomer were dissolved in 50mL of deionized water to obtain a monomer aqueous solution, and then the monomer aqueous solution was added to 8.25g of Span-80 and 6.75 g of Tween-80 was emulsified in 135 g of cyclohexane for 15 min under a high-shear homogeneous emulsifier to obtain an emulsion. Add the above-mentioned emulsion into a 500mL four-necked bottle equipped with a stirrer, a thermometer, a dropping funnel, and a ventilation tube, and after stirring for 20 minutes with nitrogen and deoxygenation, add dropwise an aqueous solution containing 0.06g of potassium persulfate and 0.02g of sodium bisulfite 10 mL, control the reaction temperature to 45°C, and stop the reaction after 4 hours of constant temperature. Add acetone to precipitate, filter under reduced pressure, wash with acetone twice, and filter to obtain a pow...
