Abstract

Oxidative stability of high density polyethylene (HDPE) containing C-alkylcalix[4]pyrogallolarenes was compared with the oxidative stability of HDPE containing 1,2,3-trihydroxybenzene (pyrogallol) and 2,6-di-tert-butyl-4-methylphenol (BHT). The Arrhenius kinetic parameters (Ea, Z, k) of non-isothermal thermo-oxidative decompositions indicate that C-alkylcalix[4]pyrogallolarenes are effective antioxidants acting at temperatures above 150 °C.
