A copolymer comprised of glycidyl methacrylate and N,N-methylenebis(acrylamide) has been defined that can be used to coat solvent-impregnated resins (SIRs). Vinyl groups on the surface of a cross-linked macroporous support were used to anchor the polar copolymer to the surface of the bead. The coated SIR containing di(2-ethylhexyl)phosphoric acid maintained a high level of metal ion complexation (96% Cu(II)) over five cycles while the uncoated SIR dropped from 93% to 11% Cu(II) complexed in three cycles.
