The radiation resistance and resistance to heat deterioration between the commercial polyperfluoroethylene-propylene resin (Fs-46) and high molecular weight one (MW>2×10^5) were compared. The representative Fs-46 and high MW resin were treated by γ-radiation (1×10^6lu) under 0.2~3.0kPa of saturated steam at 190±2℃ for 8. 25h. and some samples after radiation treatment were then subjected to the heat deterioration at 200℃ for 4320h. It was found that the high MW copolymer can preserve the original mechanical properties while the commercial ones were destroyed. The high MW Fs-46 resin demonstrated its better properties of the radiation resistance and resistance to heat deterioration.
