Procedure

1.5 g of sodium dodecylnitrate was introduced into a 1 liter three necked flask which had been furnished with an agitator and a reflux condenser and dissolved in 300 ml of water. Next, the reaction vessel was heated to 75° C under nitrogen stream and the solution was agitated at 200 rpm. At this point, 40 g of a 3% aqueous solution of potassium persulfate was added, followed by the dropwise addition over a period of 3 hours of a solution mixture comprising 150 g of methyl methacrylate, 87.5 g of ethyl acrylate and 12.5 g of acrylic acid. A total of six 10 g lots of 3% potassium persulfate solution were added at 30 minutes intervals after the start of the dropwise addition. The reaction vessel was maintained at 75° C. for 2 hours following the completion of the dropwise addition of the monomer mixture and an aqueous dispersion of a copolymer having average molecular weight of 250,000 was obtained. This aqueous dispersion was neutralized with a 10% aqueous potassium hydroxide solution and adjusted to pH 7.0.
