Abstract

Some coordination complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn (II) metal with [4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol], has been prepared in alcoholic medium and used for photostabilizer for polystyrene. Polystyrene (PS) has been mixed with these complexes in chloroform solvent to form modified PS in (5%) w/v thickness, which containing concentration of complex 0.5% by weight were produced by the casting method from chloroform solvent. The photostabilization of PS films compounds was investigated. The light of the wavelength 365 nm with intensity (6.02∗10-9 Ein Dm-3 S-1) is used for irradiation of PS films at room temperature. The photostabilization activity of these compounds was determined by calculating the photodecomposition rate constant (Kd) for blank and modified polystyrene.
