| AbstractA five new Schiff's bases namely 1,2,4,5-tetra[-5-arylidene-1,3,4-thiadiazole-2-yl]-benzene are synthesized by condensation of 1,2,4,5-tetra-[5-amino-1,3,4-thiadiazole-2-yl]-benzene with four equivalent of appropriate aromatic aldehyde in ethanol. The compounds arecharacterized by analytical and spectral means. The activity of these compounds inphotostabilization of PVC is investigated using FTIR and UV-VIS Spectrophotometerictechniques. All these additives were act as stabilizer in PVC film. The following trend isobtained for the photostabilization effect of PVC films in the presence of these additives.SP < SH< SM< SN< SOAccording to the experimental results obtained, a propose mechanism was suggesteddepending on the structure of the additive. | ||
