Versuchsvorschrift
122.5 g of methylglycol, 83.3 g of a 60% strength aqueous solution of dimethyldiallylammonium chloride and 50 g of dimethylaminoethyl methacrylate are initially placed in a 700 ml 4-necked flask, equipped with an anchor stirrer, a thermometer, a reflux condenser and a gas inlet tube, and the pH of the mixture is adjusted to a value of 8.5 with 3.8 g of glacial acetic acid. Nitrogen is then passed in, the mixture is heated to an internal temperature of 80° C. and 0.2 g of 2,2'-azobis-(2-amidinopropane) dihydrochloride is added at an internal temperature of 60° C. and copolymerization is carried out within the temperature range from 76° to 80° C. Stirring is then continued for a further 2 hours. 22 g of a condensation product formed from 1 mol of adipic acid and 1 mol of diethylenetriamine are then added, followed by 2.052 g of epichlorohydrin in the form of a 10% strength solution in ethanol. Crosslinking of the copolymers is complete after stirring for 10 to 20 minutes at 70° C. The pH of the solution is then adjusted to a value of 7.0 by adding 1.5 g of H2SO4 (diluted with water in the ratio 1:1).
