Fullerene C60 conjugated with phenols as new hybrid antioxidants to improve the oxidative stability of polymers at elevated temperatures

Abstract

Four derivatives of fullerene C60 with covalently bonded simple phenols were tested as inhibitors of oxidation of polyethylene at elevated temperatures 150-250 °C under non-isothermal conditions. Temperatures of the start of oxidation as well as the Arrhenius kinetic parameters of overall oxidation indicate a significant improvement of the oxidative stability of composites with fullerene derivatives.
