In this study, we prepared copolymer of styrene and acetyl thiophene containing uranyl nitrate. Polymerisation is initiated by benzoyl peroxide (BPO). BPO is a free radical initiator so copolymer was prepared by free radical polymerisation. The physical properties such as softening range, solubility, permeability and adsorption of the synthesized polymer films were measured. Preparations of polymer films were confirmed by IR and NMR spectroscopy. Thermal stability is measured by thermal gravimetric analysis (TGA). Owing to the presence of metal and lone pair of electron on thiophene, the polymer films show conductivity.
