Temperature Limit for Fullerene C₆₀ as an Antioxidant in the Thermal Oxidation of Polymers

Polymeric nanocomposites containing non-covalently bonded fullerene C60: properties and applications

“…Let us mention that all antioxidants are known to lose their inhibiting potency at 270-290 C as they decompose via oxidation with oxygen; the temperature interval where fullerenes exert their stabilizing action lies at 335-340 C. Each binary fullerenepolymer system is characterized by its own temperature threshold, which is controlled by the chemical structure of a polymer. 70,71 The easier the oxidation of the polymer, the lower the temperature threshold. In particular, the temperature corresponding to the onset of intensive oxidation is 248 C for the fullerene C 60 -PS system; for fullerene-free PS, this temperature is 220 C (the DSC method).…”
