Abstract

Coordination compounds from some transition elements such as Ni(II), Cu(II), Zn(II), Ba(II), Cd(II) and Sn(II) with [2-thioacetic acid-5-phenyl-1,3,4-oxadiazole] were prepared in alcoholic medium. These compounds were used as photostabilizer for poly(vinyl chloride) films against degradation. PVC films were prepared by assorted with these complexes in tetrahydrofuran solvent, which containing 0.5% w\w concentration of complex. The casting method was used to get rid of the THF solvent. (1.052×10-8Ein.Dm-3.S-1) with wavelength ?=313nm is the intensity of light that was utilized to irradiated films at room temperature. The performance of photostabilization for these complexes estimated from calculating the photodecomposition constant (kd) for PVC films with and without additive.
