Abstract

Semi-crystalline industrial polyethylene terephthalate (PET) has been analyzed, directly or after an ionic prebombardment, by Static SIMS spectrometry using 4 keV Xe ions. The prebombardment doses cover approximately one order of magnitude from 1.8 x 1013 ions/cm2 (dose for a direct SSIMS spectrum) to 1.8 x 1014 ions/cm2. By comparing the spectra using differences it is shown that, for the mentioned doses, the major features of the appearing degradation are, on the one hand, crosslinking and/or graphitization and, on the other hand, unsaturation. These features are studied as a function of the ionic dose and the polymer characteristics.
