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

Schiff bases of hydroxy benzaldehydes with aliphatic and aromatic 1,2-diamines were resinified in HCHO in alkaline media. These resins were found to form complexes readily with Cu(II), Co(II), and Ni(I1). The materials were characterized by infrared, 'H-NMR, UV-visible (UV-vis) spectral studies, and
The synthesis, characterization and capacity studies of two chelating resins having multiple functional groups capable of coordinating to several metal ions are reported. The resins were synthesized by condensing phenolic Schiff bases derived from 4,49-diaminodiphenylsulphone and o-hydroxyacetopheno
## 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
The diazonium salts of aniline and 4,4Ј-diaminodiphenylmethane coupled with phenol and resorcinol were condensed with formaldehyde in alkaline media to yield polymeric resins. These polymers were found to readily react with metal ions like Cu 2ϩ and UO 2 2ϩ , forming polychelates. The azodyes, resin
