Abstract
The present paper reports the synthesis, characterization, ion-exchange properties and coordination aspects of the title polymer ligand. The polymeric ligand was prepared by polycondensation of 2,4-dihydroxyacetophenone with urea and formaldehyde. This newly synthesized polymeric ligand has been characterized by elemental analyses, average molecular weight determination, viscosity and TGA studies. A range of polymeric chelates with a [ML2]n type general formula have been prepared with Cu(II), Ni(II), Co(II), Mn(II), Zn(II), VO(II) and UO2(II) metal ions. Physicochemical characterizations have been made from though worthwhile to condense 2,4-dihydroxyacetophenone with urea and formaldehyde in the presence of 2M HCl as a catalyst.Keywords
