Abstract
Abstract3‐Carboxy‐4‐hydroxyacetophenone (CHAP) was polycondensed with various proportions of formaldehyde using alcoholic alkali as catalyst. The resin samples, designated as CHAP‐F, have been characterized by elemental analyses and IR spectroscopy, by estimation of their number average molecular weights (M̄n), by measurement of intrinsic viscosity, and by TGA. Polymeric metal chelates of one CHAP‐F sample with Cu2+, Fe3+, Co2+, Ni2+, and UO22+ ions have been prepared and characterized.Ion‐exchanging properties of one CHAP‐F resin sample for Fe3+, Cu2+, and Ni2+ metal ions are studied by the application of the batch‐equilibration method.
