Copolymers (2-H, 4-MPPUF) were synthesized by the condensation of 2-hydroxy, 4-methoxy-propiophenone (2-H, 4-MPP), urea (U) and formaldehyde (F) in the presence of HCl and H2S04 as catalyst with varying molar ratios of reacting monomers. The copolymers were characterized by elemental analyses, IR spectra, viscosity and TGA study. Their$$\bar M_n $$ was determined by nonaqueous conductometric titrations and vapour pressure osmometry. Chelation ion-exchange properties have also been studied employing the batch-equilibration method.
