The method comprises: (a) blending a polymeric material with an antioxidant and a peroxide cross-linking agent； and (b) consolidating the polymeric material thereby forming a consolidated, antioxidant and cross-linking agent-blended polymeric material. The polymeric material is selected from ultrahigh molecular weight polyethylene, high density polyethylene, low density polyethylene, linear low density polyethylene, and mixtures and blends thereof. The consolidation comprises compression molding or direct compression molding the polymeric material. Such material can be used in medical implant.1/26 Si g R Figure 1
