CF2=CFO(CF2CFY1O)p−(CF2CF2CF2O)q−Rf (1)
(式中、Y1はFまたはCF3を表し、Rfは炭素数1〜5のパーフルオロアルキル基を表す。pは0〜5の整数を表し、qは0〜5の整数を表す。)で表される単量体、および、一般式(2):

各単量体単位の含有量は、NMR分析装置(たとえば、ブルカーバイオスピン社製、AVANCE300 高温プローブ)により測定した。
ASTM D1238に従って、メルトインデクサーG−01(東洋精機製作所製)を用いて、372℃、5kg荷重下で内径2.1mm、長さ8mmのノズルから10分間あたりに流出するポリマーの質量(g/10分)を求めた。

共重合体のペレットを、コールドプレスにより成形して、厚さ0.25〜0.3mmのフィルムを作製した。このフィルムをフーリエ変換赤外分光分析装置〔FT−IR(Spectrum One、パーキンエルマー社製)〕により40回スキャンし、分析して赤外吸収スペクトルを得、完全にフッ素化されて官能基が存在しないベーススペクトルとの差スペクトルを得た。この差スペクトルに現れる特定の官能基の吸収ピークから、下記式(A)に従って試料における炭素原子1×106個あたりの官能基数Nを算出した。

共重合体中の金属含有量総量を測定するために、ペレットを白金るつぼに秤取り、バーナーおよび電気炉で順次灰化した。灰化物を硝酸で加熱分解し、希硝酸で処理して定容とした。希硝酸で白金皿を洗浄し、洗浄液をICP発光分光分析法(ICP質量分析装置 Agilent Technologies社製 Agilent 8800)にて分析した。なお、金属含有量の測定では、金属成分毎に検出限界値が存在する。金属含有量が検出限界値未満である金属成分については、その検出限界値を金属含有量の総量に加算した。
下記共重合体20gをガラス容器(50mlスクリュー管)に入れ、HPM38(Crめっき)またはHPM38(Niめっき)により形成された金属柱(5mm四方の四角形状、長さ30mm)を、ガラス容器に共重合体に触れないようにぶら下げた。そして、ガラス容器にアルミホイルで蓋をした。ガラス容器をこの状態のままオーブンに入れ、380℃で3時間加熱した。その後、加熱したガラス容器をオーブンから取り出し、室温まで冷却を行い、金属柱表面の腐食の程度を目視で観察した。腐食程度は次の基準で判定を行った。
○:腐食が観察されない
△:わずかに腐食が観察される
×:腐食が観察される
