Poly (vinyl phosphonic acid-co-methacrylic acid) was synthesized by suspension polymerization.The structures of poly (vinyl phosphonic acid-co-methacrylic acid) were confirmed by FT-IR (Fourier transform infrared) spectroscopy. The peaks of poly (vinyl phosphonic acid-co-methacrylic acid) were assigned 927 cm-1 and 1546 cm-1 to the P-OH group of phosphonic acid and N-H bending peak of N, N’-methylene-bis-acrylamide, respectively and the carbonyl peaks of methacrylic acid and N, N'-methylen-bis-acrylamide assigned1747 cm-1 and1680 cm-1. The water uptakes were obtained range from 50~200%, and the ion exchange capacity was obtained 0.8 meq/g at an optimum condition. |
