すなわち、パーフルオロ(8−シアノ−5−メチル−3,6−ジオキサ−1−オクテン)、すなわち8−CNVEである。
ならびに式
(式中、Aは、SO2、O、CO、1〜6個の炭素原子のアルキレン、1〜10個の炭素原子のパーフルオロアルキレン、または2つの芳香族環をリンクする炭素−炭素結合である)を利用する。上記の式XIIおよびXIIIのアミノおよびヒドロキシルまたはチオ基は、ベンゼン環上で互いに隣接しており、A基に対して、交換できるようにメタ位およびパラ位である。好ましくは、硬化剤は、4,4´−[2,2,2−トリフルオロ−1−(トリフルオロメチル)エチリデン]ビス(2−アミノフェノール);4,4´−スルホニルビス(2−アミノフェノール);3,3´−ジアミノベンジジン;および3,3´,4,4´−テトラアミノベンゾフェノンからなる群から選択された化合物である。これらのうちの1番目のものは、最も好ましく、ビス(アミノフェノール)AFと呼ばれる。硬化剤は、アンジェロ(Angelo)の米国特許公報(特許文献9)に開示されているように調製することができる。ビス(アミノフェノール)AFは、好ましくは硝酸カリウムおよびトリフルオロ酢酸を用いた4,4´−[2,2,2−トリフルオロ−1−(トリフルオロメチル)エチリデン]−ビスフェノール(すなわち、ビスフェノールAF)のニトロ化、続いて好ましくは溶媒としてエタノールおよび触媒として触媒量の炭素担持パラジウムを用いた接触水素化によって調製することができる。硬化剤のレベルは、加硫物の所望の特性を最適化するように選択されるべきである。一般に、パーフルオロエラストマー中に存在している硬化部位すべてと反応するのに必要とされた量に対してわずかに過剰の硬化剤を使用する。通常は、エラストマー100部当たり硬化剤0.5〜5.0重量部が必要である。好ましい範囲は、1.0〜2.0phrである。
(粘着力)
タイプAS−214のo−リングで粘着性を測定した。o−リングを2枚のステンレス鋼板で挟みジグで25%圧縮した。次いで、ジグを、空気オーブン中、300℃で16時間配置した。その後、ジグをオーブンから取り出し、室温で3時間放冷した。次いで、板をインストロン(Instron)に取り付け、板を引き離すのに必要とされた力を測定した。粘着力としては、150N未満は許容でき、150N超は許容できない。
フィルムで被覆されたタイプAS−214のo−リングをジグで使用して、ヘリウムを充填可能なチャンバと真空下のチャンバとの間のシールを形成した。o−リングを25%圧縮した。真空チャンバをアルバックヘリオット(ULVAC HELIOT)301ヘリウム漏れ検出器に連結した。試験は、ヘリウムがヘリウムチャンバに導入されてから、He検出器で少なくとも10-10Pam3/秒の速度で検出されるまでの所要時間を測定することによって行った。所要時間としては、30秒超は許容でき、30秒〜15秒は限界ぎりぎりであり、15秒未満は許容できない。
この実施例で使用する硬化パーフルオロエラストマー物品は、テトラフルオロエチレン、パーフルオロ(メチルビニル)エーテル、およびパーフルオロ(8−シアノ−5−メチル−3,6−ジオキサ−1−オクテン)の単位の共重合物を含むパーフルオロエラストマーで作製したタイプAS−214のo−リングであった。パーフルオロエラストマーに加えて、o−リングは、6.5phrのTiO2および3phrのSiO2も含有した。
