Ammonium → Isopropenyl Phosphonic Acid Hydroxypropylacrylate Methyl Acrylate

Participants

Reaction Steps

Aqueous isopropenyl phosphonic acid (71 g, 54%, 0.3 mole), hydroxypropylacrylate (13 g, 0.1 mole) and methyl acrylate (5 g, 0.06 mole) were mixed with 121.6 g water containing 6 g of ammonium pursulfate. After sparging with nitrogen for 1/2 hour, the mixture was heated to reflux for 11/2 hours. An additional 6 g of initiator was added followed by an equivalent period of reflux. The final product had a pH of 0.65. The 31PMR showed significant polymeric absorptions at -32.4 and -24.3 ppm.
