Depolarization-current study of low-density polyethylene containing an antioxidant

Abstract

Thermally stimulated depolarization currents in low-density polyethylene containing Irganox 1076 are investigated. The thermal sampling technique has been used to study the elementary processes constituting β and γ relaxations. Irganox 1076 is found to increase the intensity of β and γ peaks and not to change the activation parameters. The participation of the antioxidant in the molecular relaxation processes is discussed.
