REMOVAL OF METAL IONS WITH IMPACT ON THE ENVIRONMENT BY WATER-INSOLUBLE FUNCTIONAL COPOLYMERS: SYNTHESIS AND METAL ION UPTAKE PROPERTIES
The crosslinked resins poly(4-acryloylmorpholine-co-4-vinyl pyridine) P(AMo- VPy), poly(N-(3-dimethylamino)propylmethacrylamide-co-4-vinyl pyridine) P(NDAPA-VPy), and poly((3-dimethylamino)propylacrylate-co-4-vinyl pyridine) P(DAPA-VPy) were obtained by radical polymerization. The resins were comple...
