The current study examined thermal oxidation kinetics of LDPE films. method could be applied to a preliminary evaluation composites stability in the environment. treated films were investigated order find out how temperature and degree (solely synergistically) influenced on crystallinity (XRD DSC methods) average crystallite size method) Two ranges studied. Samples exposed same range (85°) time periods (50, 100, 200, 300 400 hours respectively), but different atmospheres (argon oxygen). It was concluded that at first stages thermooxidation process, factor predominantly, then captured oxygen effected increased size.
