PVC Films Performance Stabilized By Dibutyltin (IV) Complex For Sustainable Environment

Abstract

Abstract A new tin(IV) complex was synthesized to inhibit the effect of UV light on PVC films. The new dibutyl tin(IV) complex coordinated to captopril as a ligand (Bu2SnL2) were used as additive to reduce the deterioration of PVC films under irradiation of UV light. Tin (IV) complex efficiency was examined under accelerated UV irradiation conditions for 300h at ambient temperature. The shifts in the FTIR index of hydroxyl, carbonyl and carbine, in addition to changes in weight, viscosity and surface morphology was used to evaluate the performance of the new complex as a photostabilizer for PVC films.
