Abstract
Modified PTFE is produced by exposing a starting PTFE to an ionizing radiation for a total dose of at least 100 kGy in the absence of oxygen at a temperature not lower than the crystal melting point of the starting PTFE. The thus modified PTFE is improved in radiation resistance and has rubber characteristics.
