Procedure

A solution was prepared of 6.0 g of sodium dodecylsulfate in 300 mL of deoxygenated water. N-1-octylacrylamide, 1.492 g, was dissolved in this solution followed by 13.98 g of acrylamide, 13.33 g of DMA, 14.94 g of N-vinylpyrrolidinone (NVP) and 41.81 g of sodium acrylamido-2-methylpropane sulfonate. The resulting solution was carefully transferred to a 1 L Morton style resin kettle fitted with a chilled water condenser, thermometer, inert gas sparger and mechanical stirrer. The temperature was adjusted to 25 C. and polymerization was initiated by the addition of 0.108 g of 2,2'-azobis(N,N'-dimethylene-isobutyramidine) dihydrochloride. After stirring for 16 hr at 25 ±0.2 C., a 250 mL portion of the viscous solution was added to 3 L of acetone. The precipitated polymer was then masticated in a Waring blender with methanol/acetone, filtered and dried under vacuum at 30 C. The yield of polymer was 110.04 g.
