The effect of radiation dose on the gel content of chlorosulfonated polyethylene (CSM) has been investigated. The results indicated that with the same radiation dose the more the chlorine content in CSM, the easier was the CSM to be crosslinked. IR spectra study showed the importance of CCl group in CSM in radiation crosslinking.The presence of the antioxidants depressed the oxidation of CSM during irradiation. The tensile strength. and the elongation of the polymer increased with increasing radiation dose when the latter was low. A maximum value of the tensile strength appeared at about 110 kGy. It is also found that γ-irradiation in dose of 60-300 kGy showed no effect on the glass transition temperature and dielectric property of CSM.
