Procedure

To a 1-liter 3-necked flask equipped with a mechanical stirrer, reflux condenser, and thermometer were charged 102 grams of ethylene urea (40 wt %), 39 grams of ethylene glycol, and 97 grams of glyoxal (40 wt %). Initial pH of the mixture was 4.3. The mixture was stirred, heated to 70° C., and held at this temperature for four hours. The product (EEG) was a clear yellow liquid with NV %=43.6%, pH=3.9 and infinite WD. The composition was stable for at least 3 months (clear, no gellation, infinite WD).
