Comparison of stabilization by Vitamin E and 2,6-di-tert-Butylphenol (cas 19126-15-9)s during polyethylene radio-thermal-oxidation

This paper reports a compilation of data for PE+Vitamin E and 2,6-di-tert-butylphenols oxidation in radio-thermal ageing. Data unambiguously show that Vitamin E reacts with P and POO whereas 2,6-di-tert-butyl phenols only react with POO. Kinetic parameters of the stabilization reactions for both kinds of antioxidants were tentatively extracted from phenol depletion curves, and discussed regarding the structure of the stabilizer. They were also used for completing an existing kinetic model used for predicting the stabilization by antioxidants. This one permits to compare the efficiency of stabilizer with dose rate or sample thickness.
