Inhoud:
The inhibition mechanism of 2,4,6-tri-tert-butylphenol in low-density polyethylene melt oxidizing at 120, 130, 140°C was studied using the procedures developed to study complicated processes of chain oxidation and inhibition in hydrocarbon materials. At each temperature the key reactions of antioxidant action were identified and the corresponding kinetic parameters determined. The analysis showed how the effectiveness of tri-tert-butylphenol changes as a function of temperature.
