Abstract: The effects of γ-radiation on three chloro-sulfonated polyethylene (CSM) with different chlorine content have been investigated, the effects of γ-radiation on some physical properties of CSM have been discussed. The results showed that three CSM can be easily crosslinked by irradiation, the crosslinking degree related to chlorine content, at the same radiation dose, the more the chlorine content in CSM, the easier the CSM to be crosslinked, unirradiated CSM has good mechanical properties (tensile strength and elongation), the effect of irradiation dose on dielectric properties was insignificant.

Key words: CSM, Radiation crosslinking of polymer, Dielectric property, Thermal property
