Synthesis Characterization and Studies of Photodegradation of PVC Films of(4-amino-5-(2-(2,3- dimethylphenyl)aminophnyl)- 1,2,4-triazole-3-thion)with Co(II),Ni(II),Cu(II),Zn(II) and Cd(II) Matel ions

Abstract

A complexes of Co(II) , Ni(II), Cu(II), Zn(II) and Cd(II)  with 4-amino-5-(2-(2,3- dimethylphenyl) aminophnyl)-1,2,4-triazole-3-thion)(L)was prepared and evaluated as a photodegradation for rigid Poly(vinyl chloride) (PVC).  Polyvinyl chloride dissolved with metal complexes in THF solvent to form PVC films of 5% (40μm) thickness containing concentrations of the complexes 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.
