Tin(IV) Compounds as Photo-Stabilizers for Irradiated Surfaces of Poly(Vinyl Chloride) Films
Dimethyl-organotin(IV) valsartan (Me<sub>2</sub>SnL<sub>2</sub>) and dichlorostannanediyl valsartan (SnL<sub>2</sub>Cl<sub>2</sub>) complexes were synthesized, characterized, and applied as Poly(vinyl chloride) (PVC) photo-stabilizers. The complexes we...

| description | Dimethyl-organotin(IV) valsartan (Me<sub>2</sub>SnL<sub>2</sub>) and dichlorostannanediyl valsartan (SnL<sub>2</sub>Cl<sub>2</sub>) complexes were synthesized, characterized, and applied as Poly(vinyl chloride) (PVC) photo-stabilizers. The complexes were loaded within the PVC films in a weight ratio of 0.5%, and the modified films were irradiated to a UV light of 313 nm wavelength for 300 h at room temperature. The efficiency of the complexes-filled films was compared with the plain one and evaluated before and after irradiation by Fourier transform infrared spectroscopy, weight loss, gel content, change in viscosity, atomic force microscopy, and field emission scanning electron microscopy. The SnL<sub>2</sub>Cl<sub>2</sub> complex had higher activity than the Me<sub>2</sub>SnL<sub>2</sub> complex to retard the PVC’s photodegradation by several mechanisms. |
