The development of functional groups during oxidation was monitored by FT-IR spectroscopy. The photo-degradation of the pristine polymer and composites take place and the increase in hydroxyl and carbonyl groups with irradiation times, was estimated. EPDM filled LDH showed higher degradation rate than pristine EPDM, while in acidic medium EPDM/LDH showed almost equal degradation as in isolated conditions. These results show the advantages of LDHs as a filler as well as an acid killer. The effect of stabilizers is very less because of their concentration in comparison of LDH.</p>10aEPDM10alayered double hydroxides10aPhoto-oxidation10apolymer composites1 aKumar, B.1 aRana, S.1 aSingh, R., P.  uhttps://library.ncl.res.in/content/photo-oxidation-epdmlayered-double-hydroxides-composites-influence-layered-hydroxides-and-0
