(1) Purify 2-acrylamide-2-methylpropane sulfonic acid crude product until content of the impurity 2-methyl-2-propene-1-sulfonic acid is less than or equal to 100 ppm;
(2) Prepare an aqueous solution of acrylamide and purified monomer 2-acrylamide-2-methylpropane sulfonic acid, and regulate its PH to 5-10 with an inorganic alkaline compound to obtain an aqueous solution of acrylamide/2-acrylamide-2-methylpropane sulfonate monomer;
(3) Under the conditions of aqueous solution polymerization, and under the protection of an inert gas, an initiation system is exposed to the above aqueous solution of acrylamide/2-acrylamide-2-methylpropane sulfonate monomer to obtain the acrylamide/2-acrylamide-2-methylpropane sulfonate copolymer colloid;
