✦ Synopsis

Abstract

The effect of ferrocene additive concentrations on the stability of polythylene polymers under atmospheric ageing and ultraviolet irradiation is reported. At concentrations under ca 5 × 10^−3^ mol kg^−1^ polymer the ferrocene compound is shown to diminish polymer resistance to light, whereas above this concentration such a compound stabilizes the polymeric matrix. Another purpose of the work is to look into the photo‐oxidative destruction of polyethylene doped with ferrocene compound by using an EPR technique. A mechanism of photo‐oxidative destruction of polyethylene polymers in the presence of ferrocene compounds is proposed.
