Synthesis and photostability study of modified poly(vinyl.

Synthesis of PVC polymer bonded to heterocyclic units is the field of our research. A number of heterocyclic units including 1, 3, 4 - oxadiazole, 1, 3, 4 - thiadiazole, porphyrine, bipyridine have been bound with PVC, In this study we attempt to modify poly(vinyl chloride) PVC by introducing benzimidazole and benzothiazole in the backbone of the PVC chain through chlorine displacement reaction, and we hope that such modification may showes interesting changes in overall thermal stability and interesting changes in over all properties of PVC such us, photostability, optical property , dielectric properties relative to un modified PVC, according to these finding, it was planned to frame a macromolecules which combine these two heterocyclic units for their characterization and photostability toward uv light.
