Abstract
Abstract New maleimide derivatives, N-(3-hydroxy-4-acetothiosemicarbazonephenyl) maleimide (HATPM) and N-(3-hydroxy-4-acetosemicarbazonephenyl) maleimide (HASPM) have been prepared by condensation of N-(3-hydroxy-4-acetyl phenyl) maleimide with thiosemicarbazide and semicarbazide hydrochlorides respectively. These are homopolymerized and copolymerized with styrene and maleic anhydride to give chelating ion exchange resins. They are analysed by elemental analysis, IR spectral study, TGA, DSC and molecular weight measurements.
