Abstract: Epoxidised products from acid oil (AO) and oil recovered from spent bleaching earth (ORSBE) were prepared at 29°C using per acetic acid produced in situ by reacting H₂O₂ (30% v/v) with various amounts of glacial acetic acid. Ba, Cd, Pb and Zn soaps of epoxidised oils were prepared by metathesis in alcohol solution. Thermal degradation studies on poly vinyl chloride (PVC) in presence of epoxidised oils and their metal soaps were carried out under non-oxidative and oxidative conditions at 180°C. Additives retarded dehydrochlorination rate of PVC and markedly reduced unsaturation level in degraded polymer. Chain scission has been found predominant reaction that accompanied dehydrochlorination. Additives reduced average number of chain scission per polymer molecule.
