Procedure

A solution was prepared of 15 g of sodium dodecylsulfate in 500 mL of deoxygenated water. N-1-octyl-acrylamide, 0.496 g, was dissolved in this solution followed by 15.2 g of acrylamide and 14.31 g of DMA. 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 20° C. and polymerization was initiated by the addition of 0.0165 g of potasium persulfate, K2S2O8, and 0.0116 g of sodium bisulfite, Na2S2O5. After stirring for 22 hr at 20 ±0.2° C., a 333 mL portion of the viscous solution was poured slowly into 3 L of acetone. The precipitated polymer was then masticated in a Waring blender with acetone, filtered and dried under vacuum at 30° C. The yield of polymer was 8.43 g. A similar procedure was used to prepare the polymers illustrated in Table I.
