Abstract: Soluble poly(aryl ether ketone)s containing thioether moieties that provide crosslinking function group were synthesized. These polymers exhibit an excellent solubility in general organic solvent. The properties before and after irradiation were investigated by differential scanning calorimetry(DSC), thermogravimetric analyses(TGA) and gel permeation chromatography(GPC). The GPC results indicate that the irradiated polymer exhibited an increasing molecular weight with increasing the irradiation dose. The DSC and TGA results also demonstrate that the glass transition temperature and thermal stability of the irradiated polymer were higher than those of un-irradiated polymer. The tensile strength and modulus of irradiated polymer increased, while the elongation at break decreased with increasing the irradiation dose.

Key words: Poly(aryl ether ketone), Electron beam, Cross-linking, Mechanical property
