Abstract
The mechanisms of inhibiting action of 2,6-di-tert-butyl-4-methyl phen ol and 2,6-di-tert-butyl phenol in the oxidation of a melt of low-dens ity polyethylene was studied kinetically at 120, 130, and 140 degrees C and mathematical models of the mechanisms were developed. The key re actions in the mechanism of the antioxidant action were determined at each of the temperatures; the corresponding kinetic parameters were de termined. The efficiencies of these antioxidants and also of the previ ously investigated 2,4,6-tri-tert-butyl phenol were compared.
