Inorganic tin(IV) complexes as photo-stabilizer for PVC

Abstract

ABSTRACT. Five organotin(IV) complexes including captopril (ligand) were employed in small amount as photostabilizers for poly(vinyl chloride) (PVC) when irradiated by UV light. Polymer’s samples were cast into films in order to conduct the UV exposure impact. The photodegradation rate constant (k_d) of blank and organotin(IV) complexes embedded PVC specimens were investigated in this work. The k_d values of filled samples were lower than the blank one, which indicates higher stability of these embedded films. Among these additives, triphenyltin(IV) showed the highest stability effect.
