Six phenolic monomers (M1 - M6) have been synthesized, namely, potassium-3-(ortho,para)-hydroxy benzoyl dithiofor- mate (M1 and M2), (ortho,para)-(4-amino-5-mercapto-1,2,4 triazol-3-yl)-phenol (M3 and M4), (ortho,para)-hydroxy benzoic acid thiosemicarbazide (M5 and M6) and twelve novel chelating terpolymers (P1 - P12) were synthesized by ter- polymerization condensation reaction of these monomers with phenol or bis phenol-A and excess of formalin in basic medium. The monomers (M1 - M6) and their co-polymers (P1 - P12) were characterized by FT.IR, H1-NMR, elemental analysis and thermal analysis (TGA) and according to data obtained the structures of these compounds were proposed. Analytical evaluation of chelating selectivity of these polymers toward (Co2+, Cr3+, Cu2+, Cd2+, Pb2+) were achieved by batch equilibrium method, the results show that all synthetic resins have high efficiency toward (Cr3+) and less effi- ciency toward (Co2+, Cu2+, Cd2+ and Pb2+).
