配制方法:

Charge water, acrylamide, and SVS to the reactor, start nitrogen purge, and heat to 50 C. At 50 C, add the potassium persulfate catalyst and allow to mix for a few min. Charge small amount of the bisulfite solution to initiate, and heat to 75-80 C. Maintain the temperature at 75-80 C for approximately 2 h. During the heating period, add the remainder of the bisulfite solution one drop at a time.
