The photo-stabilization of polymers derived from poly(vinyl chloride) (PVC) films was investigated. The PVC and modified PVC films were produced by the casting method from tetrahydrofuran (THF) solvent. The photostabilization activities of these compounds were determined by monitoring the carbonyl, polyene and hydroxyl indices with irradiation time. The changes in viscosity average molecular weight of PVC with irradiation time were also tracked (using THF as a solvent). The quantum yield of the chain scission (Φ cs) of these complexes in PVC films was evaluated and found to range between 4.79 × 10 −8 and 7.50 × 10 −8. Results obtained showed that the rate of photostabilization of PVC in the presence of the additive followed the trend: P1 > P2 > P3 > P4 > P5
