実験手順

A one liter four necked flask equipped with a reflux condenser, a stirrer, a thermometer and a supply pipe for nitrogen gas was charged with 63.9 g. of acrylamide, 18.6 g. of diethylaminoethyl methacrylate, 3.7 g. of allyl alcohol, 10.4 g. of 35 % hydrochloric acid and 646.4 g. of deionized water. The temperature was elevated to 60°C. while supplying nitrogen gas, and then 0.82 g. of potassium persulfate dissolved in 81.2 g. of deionized water was added to the flask. The temperature was further elevated to 80°C., and at this temperature the polymerization was carried out for 3 hours. After the conclusion of the polymerization, the reaction mixture was cooled to give an aqueous solution of acrylamide-diethylaminoethyl methacrylate copolymer. The concentration, pH value and viscosity at 25°C. of the solution were 10.1 %, 6.0 and 3,700 cP, respectively.
