: The photostabilization of poly(vinyl chloride) films by New metal complexes of the ligand 4-(Benzylidene-amino)-5-pyridin-4-yl-4H-[1,2,4]triazole-3-thiol with the metal ions Cu(II), Cd(II), Sn(II), Zn(II) and Ni(II) was investigated. The PVC films containing concentration of complexes 0.5% by weight were produced by the casting method from tetrahydrofuran (THF) solvent. The photodegradation of films was investigated using UV-visible spectra. The photostabilization activity of these compounds was determined by calculating the photodecomposition rate constant (Kd) for PVC modified.
