The poly(vinyl chloride) PVC was photostabilized by gallic acid derivatives (0.5% by weight). The photodecomposition rate constant was reduced significantly in the existence of gallic acid derivatives along withPVC (blank). R1 compound was found to be the most effective stabilizer in photostabilization of PVC. The photodecomposition rate constant for PVC films containing R1 was found to be 1×10-4 compared to 8×10-4 sec-1 for PVC films in the absence of any additives. Different mechanisms of photostability for PVC films that involvegallic acid derivatives have been proposed. Article history Received:19 October 2017 Accepted: 5 january 2018
