    摘要: The present invention provides irradiated crosslinked polyethylene containing reduced free radicals, preferably containing substantially no residual free radical. Processes of making crosslinked wear-resistant polyethylene having reduced free radical content, preferably containing substantially no residual free radicals, by mechanically deforming the irradiated PE either with or without contact with sensitizing environment during irradiation and annealing the post-irradiated PE at a temperature that is above the melting point of the PE, are also disclosed herein.
