Abstract
The determination of nitroxide radical distributions within polypropyl ene plaquettes containing amine stabilisers as well as other additives , which had been irradiated under air on one surface for several month s, have been determined by an X-band EPR-Imaging apparatus. It is show n that the EPR Imaging technique represents a powerful tool for invest igating the way in which the concentration inside polymers of nitroxid e radicals changes both in time and in the space, thus providing infor mation not easily obtainable by means of other techniques.
