The first step includes preparation of copoly imine by reaction of different aldehydes with copoly acid hydrazide (1-15). The second step indicated the reaction of copoly imine with iodine in the presence of K2CO3 to give poly (N-substituted-maleimide-co-2,5-substituted-1,3.4-oxadiazole). All prepared compounds were characterized by softening points, FT-IR, and some of them by 1H-NMR and TGA, and then their Biological application was studied and some of the physical properties.}, keywords = {copoly Schiff bases,Copoly 1,3.4-oxadiazole,Biological activity}, url = {https://www.chemmethod.com/article_148298.html}, eprint = {https://www.chemmethod.com/article_148298_b1d3a20a0ffb85215aaf368997bb5835.pdf} }
