Chemical modification of PVC with Schiff Base Containing a Thiadiazole Moiety and its Influence on the Physicochemical and Morphological Properties

Chemical modification of PVC using 2-(((5-mercapto-1,3,4-thiadiazol-2-yl)imino)methyl) benzoic acid as a ligand (L) with Cu(II) and Sn(II) metals has been successfully prepared. The present study focused on modification of PVC films 2-(5-mercapto-1,3,4-thiadiazol-2-yl)imino)methyl) benzoic acid complexes. Modified Poly(vinyl chloride) films with Cu (II) and Sn (II) have been synthesized in order to investigate some transition metal complexes role in the PVC modification. The synthesized complexes were confirmed by FTIR spectroscopy, Energy-dispersive X-ray spectroscopy analysis (EDX), scanning electronic microscope (SEM) and microscope.
