Synthesis, Characterization with Studying Physical Properties by Free Radical Polymerization of Some New Resins Starting from 5-Styryl-1, 3, 4-Thiadiazol-2-amine

Abstract

Starting from  5-styryl-1,3,4-thiadiazol-2-amine[1], a variety  of Schiff  bases [2-6] prepared,   Schiff base derivatives which containing heterocyclic rings  have been synthesized [7-11]  as monomers .Then  addition  reaction( free radical polymerization)  for monomers by using AIBN as initiator in (50-70) C⁰  obtaining [12-16] resins .  All proposed structure were supported by FTIR,  solubility ,softening points , and some derivatives evaluated by 1H-NMR  ,Elemental analysis , thermal analysis (TGA,DSC), X-Ray diffraction.

Keywords:  Schiff bases, Derivatives with heterocyclic rings as monomers.
