Ultra-violet spectra studies of photodegradation of PVC films in presence of Fe(III) chelate complex Yousif, Emad Haddad, Raghad Ameer, Ameer Abbas Win, Yip-Foo PVC Triazole UV-light Fe(III) complex Photochemistry Photodegradation A complex of Fe(III) with 4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol was prepared and evaluated as a photodegradation for rigid poly(vinyl chloride) (PVC). Polyvinyl chloride dissolved with Fe(III) complex in THF solvent to form PVC films of 5% (40 μm) thickness containing different concentrations (0.01, 0.02, 0.03, 0.04 and 0.05 g) of the complex by weight. These different samples were produced by the casting method from the 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 modified PVC films against a blank.
