Abstract:
1. A process for preparing crosslinked oxidation resistant UHMWPE for use in medical prostheses comprising the steps of: (i) obtaining UHMWPE resin; (ii) combining the UHMWPE resin with both a first amount of a first additive and a second amount of a second additive, wherein the first and the second additives are different additives; (iii) consolidating the UHMWPE that has been combined with the first and second additives; and (iv) crosslinking the consolidated UHMWPE to create oxidation resistant UHMWPE, wherein the first and second additives synergistically increase the oxidation resistance of the crosslinked UHMWPE.
