Procedure

400 g of an acrylamide-ethylacrylate 80-20 copolymer were dissolved in 1200ml of water; the pH was adjusted to 12-13 by adding NaOH; 400 ml of 40% formalin were added while heating to 70° C. for 2 hours; the pH waskept at 12-13 with further addition of NaOH. After cooling the solution waspoured into 15 liters of ethanol under good stirring, the separated polymerwas filtered, washed with acetone and dried at reduced pressure. Yield: 590g of water-soluble polymer. Analytical results: free CH2O: absent; total CH2O: 18.9%; [η]: 0.36 dl/g in NaNO3N at 30° C.
