Procedure

A 34 gallon batch of a 19 weight percent potassium acrylate and 35 weight percent aqueous acrylamide solution was prepared as follows: 219 pounds of a 50 weight percent acrylamide solution was contacted with 38.4 pounds of acrylic acid, followed by the controlled addition of 58.2 pounds of a 50 percent by weight potassium hydroxide solution, 9.8 pounds of high molecular weight poly (acrylamide), P-250 (commercially available from American Cyanamid, Wayne, New Jersey 07470) in powder form was added in a controlled fashion to the aqueous solution to ensure that the powder was properly dispersed. The concentration of powdered polymer was 3 percent by weight. The thickened solution was mixed in a 100 gallon stainless steel tank with a mechanical stirrer at 48 RPM for 20 hours and remained unagitated for two additional days. Then its viscosity was measured using a Brookfield Viscometer and found to be 43,000 centipoise.
