Abstract
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.
