| Abstract | ||
| Several new –2- amino – 5 – Poly styryl – 1,3,4 – oxadiazoles were prepared from suitable polystyryl ( o- ,m- ,and p- ) methyl esters, which were converted to the corresponding acid hydrazide by their reaction with hydrazine hydrate in the presence of bromo cyanogen . Three novel of 2-amino –5- polystyryl – 1,3,4-thiadiazole were also synthesized by one step method through condensation of polystyryl ( o, m , and p ) methyl esters and thiosemicarbazide in the prescence of concentrated sulfuric acid . All the new synthesized polymers were characterized by their softening point , and spectral ( IR , UV , H- NMR and elemental analysis ) means. | ||
