Phenolic Schiff bases derived from o-, m-, and p-hydroxybenzaldehydes and 4, 4Ј-diaminodiphenyl ether were subjected to polycondensation reaction with formaldehyde. The resins were found to form polychelates readily with several metal ions. The materials were characterized by elemental analysis, GPC
## Abstract The synthesis, characterization, and metal ion uptake studies of two chelating resins with multiple functional groups are reported. The chelating resins were synthesized by condensing a phenolic Schiff base derived from 4,4′‐diaminodiphenylmethane and __o__‐hydroxyacetophenone with form
