Abstract
Description
CF2=CF−ORf (1)
(式中、Rfは、パーフルオロ有機基を表す。)で表されるパーフルオロ不飽和化合物等が挙げられる。本明細書において、上記「パーフルオロ有機基」とは、炭素原子に結合する水素原子が全てフッ素原子に置換されてなる有機基を意味する。上記パーフルオロ有機基は、エーテル酸素を有していてもよい。
上記MIT値は、ASTM D2176に準じて測定することができる。具体的には、幅12.5mm、長さ130mm、厚さ0.25mmの試験片を準備し、MIT試験機(型番12176、安田精機製作所社製)に装着し、荷重1.25kg、左右の折り曲げ角度各135度、折り曲げ回数175回/分の条件下で試験片を屈曲させ、試験片が切断するまでの回数である。
測定装置:固体19F−NMR測定装置、BRUKER社製
測定条件:282MHz(変性PTFEのCF2を−120ppmとする)
回転数30kHz
ケミカルシフト−80(−74〜−85)ppmに観測されるピークであって、変性モノマーであるパーフルオロアルキルビニルエーテル(PAVE)の−O−CF* 2−と−CF* 3のC−F*5個に由来するピークの強度
ケミカルシフト−120(−84〜−150)ppmに観測されるピークであって、PAVEのC−F*5個とテトラフルオロエチレン(TFE)由来のC−F*4個が重なっているピークの強度
ケミカルシフト−183(−178〜−191)ppmに観測されるピークであって、第三級炭素−CF2CF*(−CF2−)CF2−に由来するF*のピークの強度
第三級炭素の含有量(モル%)=100×(ピーク強度C)÷{(ピーク強度A÷5)+[ピーク強度B−ピーク強度A]÷4+(ピーク強度C)}
変性モノマーがPAVE以外のモノマーである場合も、19F−NMR測定により、第三級炭素の含有量を求めることができる。
示差走査熱量計〔DSC〕を用いて10℃/分の速度で昇温したときの融解熱曲線における極大値に対応する温度として求めた。
赤外分光分析法により特性吸収(パーフルオロ(プロピルビニルエーテル)(PPVE)の場合は1040cm−1〜890cm−1の間)から求める。
ASTM D2176に準じて測定した。具体的には、幅12.5mm、長さ130mm、厚さ0.25mmの電子線未照射又は照射後の試験片を、MIT試験機(型番12176、安田精機製作所社製)に装着し、荷重1.25kg、左右の折り曲げ角度各135度、折り曲げ回数175回/分の条件下で試験片を屈曲させ、試験片が切断するまでの回数(MIT値)を測定した。
特許第3177983号公報に記載の実施例1と同様にして得られた変性PTFEパウダー(TFE単位及びPPVE単位の合計に対して0.06質量%のPPVE単位を含み、二次融点が323℃である)を用いた。50mmφ、高さ50mmの金型に200gの上記パウダーを充填し、15MPaの圧力で両押し、圧力保持30分行って、予備成形品を得た。この予備成形品を昇温速度90℃/時で昇温後、360℃で4時間保持し、40℃/時で降温し成形品ブロックを得た。このブロックを切削加工し、0.5mm厚のシートと0.25mm厚さのシートを作成した。また、0.25mm厚さのシートで測定したMIT値の結果は1500万回であった。
得られた試験片を、電子線照射装置(NHVコーポレーション社製)の電子線照射容器に収容し、その後窒素ガスを加えて容器内を窒素雰囲気にした。容器内の温度を280℃まで昇温し温度が安定した後、電子線加速電圧が3000kV、照射線量の強度が20kGy/5minの条件で、試験片に40kGyの電子線を照射した。電子線照射前後での試験片の寸法変化は1%以下でシワの発生は無かった。
表1及び2に示す照射温度及び照射量を採用した他は、実験例1と同様にして、0.5mm厚のシートを得た。
0.5mm厚のシートを用いて、試験を実施した。染色摩擦堅ろう度試験機(安田精機製作所社製)を使用し、図2に示すように、シート21上に、摩擦子22の先端に固定したPFAシート23を設置し、両者をお互いに往復摩擦した。荷重は500g、回数は2000回(30回/分)とした。PFAシートを摩擦子から取り外し、PFAシートに付着した析出物(粉)の量を測定した。結果を表1及び2に示す。
なお、実験例5及び8では、試験中にサンプルが割れたことから、試験を中断した。実験例5及び8の結果から、放射線の照射量が大きすぎると、ダイヤフラムに通常必要とされる機械物性が得られないことが分かった。
実験例2で得られたPFAシートに付着した析出物の成分を次の方法により特定した。析出物が付着したPFAシートをホットステージ上に載置し、PFAの融点である305℃以上かつ変性PTFEの融点である323℃未満に加熱し、偏光顕微鏡(オリンパス社製BX51)により観察したところ、PFAシートの溶融が始まったが、析出物は溶融しなかった。更に変性PTFEの融点以上に加熱すると、析出物が溶融した。従って、PFAシートに付着した析出物は変性PTFEの析出物であることが分かった。
0.5mm厚のシートの19F−NMR測定を行うことにより求めた。算出方法は上述のとおりである。

13 ボディー
14 シリンダ
15 ピストンロッド
16 弁座
21 シート(サンプル)
22 摩擦子
23 PFAシート
ASTM D2176に準じて測定した。具体的には、幅12.5mm、長さ130mm、厚さ0.25mmの電子線未照射の試験片を、MIT試験機(型番12176、安田精機製作所社製)に装着し、荷重1.25kg、左右の折り曲げ角度各135度、折り曲げ回数175回/分の条件下で試験片を屈曲させ、試験片が切断するまでの回数(MIT値)を測定した。
