Abstract
A kinetic investigation of the inhibition mechanisms of 2,6-di-tert-bu tylphenol and 2,6-di-tert-butyl-4-methylphenol in a low-density polyet hylene melt oxidizing at 120, 130 and 140 degrees C has been carried o ut and the mathematical models of the mechanisms developed. At each te mperature the key reactions in the mechanisms of action of the antioxi dants were identified and the corresponding kinetic parameters determi ned. The comparison of the efficiencies of these antioxidants and 2,4, 6-tri-tert-butylphenol studied earlier has been carried out.
