he radiation-induced crosslinking and oxidation reaction when the polymethylphenylene sulfide (PMPS) is irradiated by the lelectron beam at R. T. in air are investigated by XPS
IR
DSC and TG. The radiation crosslinking take place on the benzene ring. The shake-up degree of the irradiated PMPS decreases due to the crosslinking. XPS can use to determine gelation dose of the polymer. The irradiated PMPS produces ph-SO-ph
