Copolymer resin (2,4-HADF-III) synthesized by the condensation of 2,4-dihydroxyacetophenone and dithiooxamide with formaldehyde in 3:1:4 mol ratio using hydrochloric acid as a reaction medium, were proved to be selective chelation ion-exchange copolymers for certain metals. The synthesized copolymer resin was characterized by elemental analysis, TGA, FTIR, electronic absorption and 1H NMR spectroscopy. The physic-chemical parameters have been evaluated for the copolymer resin. The thermal stability of the copolymer was analyzed by thermo gravimetric analysis. The activation energy and the order of the reaction were calculated for 2, 4-HADF-III by the Freeman-Carroll method. 2, 4-HADF-III possesses antimicrobial activity for certain bacteria such as Staphylococcus aureus, Escherichia coli, and fungi Aspergillus niger, Candida albicans. The semi crystalline nature of the synthesized copolymer was established by scanning electron microscopy (SEM). The electrical property of the copolymer was also evaluated at various concentrations and temperatures.
