Oxidation-resistant and wear-resistant polyethylenes for human joint replacements and methods for making them

摘要

The present invention relates to polyethylenes. It discloses methods for enhancing the wear resistance of polyethylenes without inducing oxidative degradation, by crosslinking oxidation-resistant polyethylenes. The polyethylenes disclosed herein are useful for making articles such as medical implants, for example, components of artificial joints such as acetabular cups.
