반응 단계
Aqueous isopropenyl phosphonic acid (47 g, 54%, 0.2 mole), hydroxypropylacrylate (26 g, 0.2 mole) and maleic anhydride (5 g, 0.05 mole, neutralized to pH 5 in 50 ml water) were mixed with 82.6 g water in a resin kettle under nitrogen. Ammonium persulfate (6 g) was added followed by 11/2 hours of reflux. An equivalent amount of initiator was added and the reflux period repeated. The final product was yellow with a pH of 0.99. The 31PMR showed polymer absorptions centered at δ=-34, -32.3 and -28.8 ppm.
