The effect of ultraviolet (UV) light on the thermooxidative stability
of Linear Low Density Polyethylene(LLDPE) films was studied. LLDPE was
stabilized with phenolic type antioxidant known as Irganox 1010, hind
ered amine light stabilizer known as Chimmasorb 944 and phenolic type
gamma stabilizer. The influence of these additives on the thermooxidat
ive stability of gamma and UV irradiated LLDPE were investigated by is
othermal Differential Scanning Calorimeter (DSC). The oxidation induct
ion time (OIT) experiments indicate that antirad free LLDPE films whic
h contains antioxidant and UV stabilizer are more sensitive to gamma a
nd UV radiation. On the other hand, films which contain antirad and ir
radiated to different doses of gamma-radiation demonstrated improved t
hermooxidative stability.
