Synthesis and characterization of novel subs. -1,3,4-thiadiazolependant on modified poly (5-Vinyl Tetrazole-Co-MA)‎

الملخص EN

New polymers were prepared from a monomer (5-vinyl-1H-tetrazole), which was prepared from acrylonitrile with sodium azide in the presence of ZnCl2.Another monomer (Methyl acrylate) was also used.

Co-monomers were polymerized usingBPO as initiator.

The second step was the preparation of copoly acid hydrazide from the reaction of compound2 with hydrazine hydrate, followed by the reaction with carbon disulphide in the presence of KOH to obtain copoly (5-subs.-2-mercapto-1,3,4-thiadiazole).

Next,compound4 was reacted with chloroacetyl chloride to yield compound4 5 which was reacted with (hydrazine hydrate , phenyl hydrazine and 2,4-di nitro phenyl hydrazine) as shown in scheme(1).

Physical properties of all the prepared copolymers were characterized by FT-IR and, in certain cases,by1HNMR spectroscopy.
