Abstract
A novel water-soluble polymer containing phosphorus poly(sodium p-methacryloylaminobenzylphosphonate) was synthesized by free radical polymerization in the presence of K2S2O8 as initiator, in water as solvent at 70°C with a 48 h reaction time. The new monomer used for the polymerization was synthesized by reaction between sodium aminobenzylphosphonate and methacryloyl chloride at 4°C in methanol with a yield of 78.3%. The compounds, monomer and polymer, were characterized by IR, 1H-NMR and potentiometric titrations. The new monomer and polymer reported here are important because they are very water-soluble and contain a versatile ligand, –PO(ONa)2, which could be used in environmental applications. The polymer possibly could be used as a metalchelating polymer or as flocculant.
