실험 절차

Aqueous isopropenyl phosphonic acid (47 g; 54%, 0.2 mole) and aqueous acrylamide (28 g, 50%, 0.2 mole) were mixed in a resin kettle as previously described. Ammonium persulfate (6 g) and an additional 84 g of water were then added. The solution was sparged with nitrogen for 1/2 hour and heated to reflux. After 11/2 hours, an additional 6 g of initiator was added followed by an additional 11/2 hours of reflux. The aqueous product was yellow with a final pH of 1.3. The 31PMR showed polymeric absorptions at δ=-30.2 to -33.7 ppm and -25 to -29 ppm.
