Using the same polymerization apparatus as described in Example 1, 17.1 g (0.13 mole) of hydroxypropylacrylate and 49.8 g (0.41 mole) of isopropenylphosphonic acid in 202.5 g water (neutralized to pH 2.5) was heated to reflux with 6 g of ammonium persulfate. After 2 hours of reflux an additional 6 g of initiator was added followed by 2 hours of reflux. The final pH of the brown solution was 2.7. The 31PMR spectrum of the product had polymer absorptions at -30 to -33 ppm and -24 ppm.
