Description
本出願は、2007年9月4日に出願した米国特許仮出願第60/982,978号明細書の利益を主張するものである。該出願の開示は、参照によりその全体が組み込まれる。
γ線滅菌したUHMWPEを圧縮成型してシート状とし(GUR(登録商標)1020、Quadrant社製、ドイツ)、機械加工し、不活性ガス雰囲気中で包装して3Mradの線量でγ線滅菌した。UHMWPE樹脂粉末を0.03、0.05または0.1wt%のα-トコフェロールと混合することによってビタミンEをブレンドした試料を作成し、圧縮成型してブロック状とし、空気中で7〜20Mradでγ線照射し、機械加工して所望の形状とした。試料のいくつかは追加的に3Mradの線量でγ線滅菌した。照射後の熱処理は行わなかった。
