Embodiment 1
[0075] This example is used to illustrate the polymer with surface active function and its preparation method according to the present invention.
[0076] Adopt aqueous solution polymerization method, in the adiabatic polymerization reactor that has surface thermocouple, add 0.25g as the structural monomer GNR-1 shown in formula (13) (Nantong Hantai Chemical Co., Ltd.) as water-soluble surface active monomer, 19.75 g acrylamide, 5.0 g of 2-acrylamido-2-methylpropanesulfonic acid and distilled water, based on the total content of monomers and distilled water, the total content of monomers is 10% by weight, fully stirred into the polymerization reaction bottle The solution in the solution becomes a transparent solution. Then add 25 mg of auxiliary agent urea, 75 mg of disodium edetate, 1 mL of ammonia water and 10 mg of isopropanol, and at the same time adjust the pH value of the system to 6 with sodium hydroxide, and feed high-purity nitrogen with a volume concentration of 99.9...
Embodiment 2
[0080] This example is used to illustrate the polymer with surface active function and its preparation method according to the present invention.
[0081] Adopt aqueous solution polymerization method, in the adiabatic polymerization reactor that has surface thermocouple, add 0.1875g structural monomer GNR-1 (Nantong Hantai Chemical Co., Ltd.) as shown in formula (13) as water-soluble surface active monomer, 24.1875 g acrylamide, 13.125 g of 2-acrylamido-2-methylpropanesulfonic acid and distilled water, based on the total content of monomers and distilled water, the total content of monomers is 15% by weight, fully stirred into the polymerization reaction bottle The solution in the solution becomes a transparent solution.
