Abstract
Gas mass spectrometry was used to quantify the gas release with exposure doses up to 4000Â kGy for the pure material and 10Â 000Â kGy for the industrial polymer: the evolution with dose is weak and is increasing only in the case of carbon dioxide. The in-chain modifications were identified by infrared spectroscopy or X-ray photoelectron spectroscopy, and correspond probably mainly to the formation of hydroperoxides, hydroxyls and ketones, along with alkenes. By GC-MS or thermodesorption analyses, oxidation products trapped in the polymer matrixes are identified and are esters, carboxylic acids, alcohols, an aromatic molecule and oligomers.
