This work examines the effect of impregnating capacitor-grade polypropylene film with an aromatic hydrocarbon fluid with a view towards assessing the response under radiation of the relevant properties of the film. Monoisopropyl biphenyl (MIPB)-impregnated polypropylene film was exposed in air to 1 MeV electrons to different doses and the post-radiation effects on the electrical, mechanical, morphological and chemical properties were evaluated. The results obtained indicate that the oil-impregnated films remain relatively stable even at the highest dose of 10/sup 8/ rads. This is in contrast to the results reported earlier for dry polypropylene films which underwent degradation primarily due to chain scission and oxidation. In the present instance, it is believed that impregnation of the film has inhibited the diffusion of oxygen and consequently favored crosslinking. The chemical characterizations as well as the changes in some of the measured properties of the film seem to corroborate this belief.
