Into a five-liter, three-necked, round-bottom flash (equipped with a mechanical stirrer, nitrogen inlet tube, thermometer, condenser and monomer inlet tube) were charged 1721.6 grams of water. The water was stirred and sparged for at least 45 minutes with a stream of nitrogen (1200 cc./min.) while heating to 80° C. Emulsifier (4.8 grams of Aerosol OT-75) was charged to the vessel. A solution of monomer feed was prepared by: mixing in a beaker 509.4 grams diacetone acrylamide, 389.4 grams butyl acrylate, 3.0 grams acrylic acid, 198 grams ethyl acrylate, 198 grams carbomethoxymethyl acrylate and 3.2 grams Aerosol OT-75; placing the mixture in a 35° C. water bath; stirring the contents to facilitate dissolution, while maintaining the temperature below 25° C.; and filtering the resulting solution. A solution of initiator was prepared by mixing 40 mls. of water and 7.3 grams ammonium persulfate and the initiator solution was set aside.
