Summary

         This thesis includes preparation and identification of some new compounds and polymers according to these steps :

1- Synthesis of some mono and di amine derivation [1-10] and some of them contained heterocyclic ring.

2- The reaction of amino derivatives [1-10] with maleic anhydride in different solvents to produce the corresponding maleamic acid derevatives [11-20].

3- The maleamic acids has been converted in to maleimides derivatives by using acetic anhydride and anhydrous sodium acetate [21-30].

4- Transforming acid hydrazide [1,2] to xanthate salt and then to be converted to bis-1,3,4-thiadiazole-2-thiol and then polymerized by thionyl chloride and by brome.

5- Xanthate salts that has been derived from acid hydrazids [1-4] are converted to corresponding bis 1-amino-1,3,4-triazole-5-thiol through the reaction with hydrazine [37-40]

6- Polymerization of bis-triazole [37-40] with diacids chlorides to produce the polymers that contain triazole ring fused with thiadiazole ring [41-56].

7- The reaction of bis triazole [37-40] with paramethoxy cinnamic acid to produce derivatives containing triazole ring fused with thiadiazole ring [57-60].

These compound identified by UV and IR spectroscopy and and some of these by H¹ NMR spectroscopy and C.H.N elemental analysis.
