Abstract

Three novel phosphate esters have been synthesized and characterized by utilizing several techniques. ¹H NMR, ³¹P NMR and FTIR spectroscopies show all need peaks to confirm the formation of target compounds. The synthesized materials were used as photo-stabilizers of PVC and they show very good results to stop the photo-degradation compare to blank PVC. The photo-stabilizers were used in few amounts about 0.5% by weight and the prepared films were irradiated for 500h by UV light. Different procedures were used to demonstrate the efficiency of phosphate esters as photo-stabilizers such as FTIR method, weight loss, and microscopic images. Compound 3 exhibits the best efficiency as an excellent inhibitor of photo-degradation for PVC films. Optical microscopy study demonstrated that using these additives keep the polymeric film surface smoother with fewer cracks after irradiation by UV light compare to blank polymer.
