[材料]
[UHMWPE]
使用したUHMWPEの、ISO 1628−3に準拠して測定された固有粘度は27dl/gであり、これはMargoliesの式、Mw=53700×[I.V]1.49を用いて計算される分子量730万g/molと一致する。
1)ビタミンE(DSM Nutrional Productsから入手したαトコフェロール)、
2)ポリ{[[6−[(1,1,3,3−テトラメチルブチル)アミノ]−s−トリアジン−2,4−ジイル][(2,2,6,6−テトラメチル−4−ピペリジニル)イミノ]−ヘキサメチレン[(2,2,6,6−テトラメチル−4−ピペリジニル)イミノ]]}(Ciba Specialty Chemicalsから入手したChimassorb(登録商標)944)、
3)1,3,5−トリアジン−2,4,6−トリアミン、N,N”’−[1,2−エタンジイルビス[[[4,6−ビス[ブチル(1,2,2,6,6−ペンタメチル−4−ピペリジニル)アミノ]−1,3,5−トリアジン−2−イル]イミノ]−3,1−プロパンジイル]]−ビス[N’,N”−ジブチル−N’,N”−ビス(1,2,2,6,6−ペンタメチル−4−ピペリジニル)](Ciba Specialty Chemicalsから入手したChimassorb(登録商標)119)、
4)1,6−ヘキサンジアミンの、2,4,6−トリクロロ−1,3,5−トリアジンとのN,N’−ビス(2,2,6,6−テトラメチル−4−ピペリジニル)−ポリマー、3−ブロモ−1−プロパンおよびn−ブチル−1−ブタンアミンおよびN−ブチル−2,2,6,6−テトラ−メチル−4−ピペリジンアミンとの酸化、水素化反応生成物(Ciba Specialty Chemicalsから入手したTinuvin(登録商標)NOR 371)。
安定剤を溶媒ブレンドによってUHMWPEに加えた。安定剤をまずクロロホルムに溶かした溶液(約100ml/ポリマー100g)としてポリマーに加え、第二ステップにおいてそのクロロホルムを蒸発させた。
内側にアルミニウム被膜を有する紙袋中に真空密閉された棒材試料上へ窒素下でγ線照射(線量25、75、および150kGray(kGy))によって照射を行った。膨潤試験用の試験試料を準備するために、照射済みの、後で切削加工してより小さい試験試料にされる棒材試料を調製した。
粉末を圧縮成形してISO 11542−2に準拠した試料にした。
引張試験用および色度測定用の試料を、通気オーブン(Binder FDL115)中で110℃において2週間老化した。
架橋密度は、照射済み棒材試料から切削加工した寸法5mm×5mm×5mmの試料を用いてASTM F2214−02に準拠して測定した。これらの試料をo−キシレン中での膨潤を受けさせた。
色度測定は、ISO 7724−1−2−3(CIELAB、D65、10o、d8)に準拠して行った。この測定は、Minolta分光光度計で黒色バックグラウンドを用いて反射によって行った。照射および老化後の棒材試料から切削加工した厚さ1mmのプラークを試料として用いた。
引張試験(破断点伸びおよび極限引張強さ)は、ISO 527に準拠して行った。
酸化指数は、5mm×5mm×5mmの立方体から切り取った約100μmのクープ(coupes)上での透過において測定される赤外スペクトルから求めた。スペクトルは、20回のスキャンおよび4cm−1の分解能を使用してPerkin Elmer Auto Image上に記録した。このスペクトルを、ASTM F2102−06と同様に1370cm−1(1330〜1370、基準1400cm−1)に正規化した。酸化指数は、1680〜1765cm−1から推論されるベースラインを用いた1717cm−1におけるピーク高さとして定義した。
