Abstract
The change in mechanical properties induced by irradiation of electron (2 M eV), proton (10 and 20 MeV), He2+ (20 and 50 MeV), and 220 MeV C5+ ions wer e studied for polymer films of polyethylene (PE), bis-phenol A based polysu lphone (PSF) and polyethersulphone (PES). There is no difference between th e irradiations of proton and electron in the mechanical properties for PE c ompared by absorbed dose. On the contrary, in aromatic polymers as PES and PSF, the decrement in the tensile strength and elongation with dose is extr emely depressed in the irradiation of ion. It was found from the measuremen ts of gel fraction and glass transition temperature that the probability of crosslinking and/or chain scission depends on linear energy transfer (LET) .
