A one liter Morton style resin kettle, fitted with a chilled water condenser, thermometer, nitrogen sparger and mechanical stirrer was charged with 500 ml of purified water. The water was refluxed for 1 hour with a nitrogen purge and then cooled to room temperature. Acrylamide, 9.886 g (0.14 mole), 4.81 g (0.37 mole) of sodium vinyl sulfonate as a 25% solution in water, 0.33 g (0.002 mole) of N-octylacrylamide and 15 g of sodium dodecyl sulfate (SDS) were charged into the flask. The reaction solution was heated to 50° C. and 0.01 g potassium persulfate was added. After 17 hours at 50° C. and 300 rpm stirring, the viscous solution was slowly poured into 3 L of methanol and the precipitated polymer was isolated by filtration. The polymer was then masticated in a Waring blender with 2 L of methanol for 30 seconds, filtered and dried under vacuum at room temperature. The yield of the polymer was 10.9 g.
