An oxidation-resistant, homogenized polymeric material and a method for producing a medical filler comprising a polymeric material, such as ultra high molecular weight polyethylene (UHMWPE). Solidified polyethylene (eg, UHMWPE) is doped with an antioxidant before, during, or after crosslinking the solidified polyethylene, followed by the addition of the antioxidant-doped polyethylene in a supercritical fluid. Annealing. [Selection] Figure 4 |
