In a 300 cc capacity round bottom flask equipped with a stirrer were put 57.5 g (0.5 mole) of N-methylolmethacrylamide and 50 cc of water and, as a polymerization inhibitor, 500 mg of hydroquinone. On the other hand, 43 g (0.5 mole) of morpholine were gradually added thereto while stirring. Afterwards, the contents were stirred for 1 hour at 50°-60°C. Finally, the reaction mixture was concentrated and then was recrystallized from ethyl acetate. m.p.; 78.0°C. Yield: 48.3 g (52.5%).
