  • Abstract
    The mechanism of O2 enhanced AC aging of impregnated PP (polypropylene) films is elucidated. Analysis by gas chromatography of the liquid and by FTIR (Fourier-transform infrared) of the polymer show an electrically enhanced oxidation rate of liquid and polymer. The electrical stress acts mainly at the initiation step by creating the first radicals. The oxidation byproducts of the liquid do not influence the degradation rate, and AC aging of PP films is mainly due to the scission of macromolecular chains greatly enhanced by O2
