preparation example 1
[0051] Preparation Example 1 Use petroleum ether as the continuous phase and Tween 60: Span 40 = 1:1 as the compound emulsifier to prepare the oil phase. According to the mass ratio of acrylamide (AM): dimethylhexadecyl (2-methyl Acrylamidopropyl) ammonium bromide (AM16):fumaric acid (FA)=60:5:10 disperses the monomer in water, the total mass concentration of the monomer is controlled at 40wt%, and the aqueous phase is prepared.
[0052] Under the condition of stirring and nitrogen, slowly add the water phase into the oil phase, the volume ratio of the oil phase and the water phase is 1.7:1, raise the temperature to 50°C, and then add 0.7wt% of the total mass of the monomers Sodium bisulfate and peroxide According to the aqueous solution of the composite initiator of ammonium sulfate with a mass ratio of 1:2, heat preservation and react for 6h, cool to room temperature and discharge to obtain a solution of the copolymer, break the emulsion with ethanol, and wash with a solvent ...
preparation example 2
[0055] Other conditions and steps are the same as in Preparation Example 1, except that dimethyltetradecyl (2-methacrylamidopropyl) ammonium bromide (AM14) is used to replace dimethylhexadecyl (2-methyl Acrylamidopropyl) Ammonium Bromide (AM16).
preparation example 3
[0057] Other conditions and steps are the same as in Preparation Example 1, except that dimethyloctadecyl (2-methacrylamidopropyl) ammonium bromide (AM18) is used to replace dimethylhexadecyl (2-methyl Acrylamidopropyl) Ammonium Bromide (AM16).
