3,3’−ジスルホン酸ナトリウム−4,4’−ジクロロジフェニルスルホン(略号:S−DCDPS)6.9499g(14.15mmol)、2,6−ジクロロベンゾニトリル(略号:DCBN)9.7340g(56.59mol)、4,4’−ビフェノール(略号:BP)6.5860g(35.37mmol)、ビス(4−ヒドロキシフェニル)スルフィド(略号: BPS)7.7199g(35.37mmol)、炭酸カリウム10.7542g(77.82mmol)、乾燥したモレキュラーシーブ3−A 7gを200ml四つ口フラスコに計り取り、窒素を流した。80mlのN−メチル−2−ピロリドン(略号:NMP)を入れて、150℃で30分撹拌した後、反応温度を195−200℃に上昇させて系の粘性が十分上がるのを目安に反応を続けた(約10時間)。放冷の後、沈降しているモレキュラーシーブを除いて水中にストランド状に沈殿させた。得られたポリマーは、沸騰水中で1時間洗浄した後、乾燥した。ポリマーの対数粘度は1.08dL/gを示した。重水素化ジメチルスルホキシド中室温で測定した1H−NMRスペクトルを図1に示した。ポリマー7gをNMP28gに溶解し、ホットプレート上ガラス板に約400μm厚にキャストして80℃で0.5時間、120℃で0.5時間、150℃で0.5時間加熱した後、窒素雰囲気の150℃のオーブン中で1時間乾燥し、ガラス板からフィルムを剥離した。得られたフィルムは室温の純水に1日浸漬した後、2mol/Lの硫酸水溶液に2時間浸漬した。その後、洗浄水が中性になるまでフィルムを純水で洗浄し、空気中に放置して乾燥して、イオン交換膜を得た。得られたイオン交換膜について評価を行った。
BPSの代わりに、4,4’−チオビスベンゼンチオール(略号:TBT)4.6054g(18.39mmol)を用い、BPの量を9.7472g(52.35mmol)に変更した他は実施例1と同様にしてイオン交換膜を作製し評価を行った。
S−DCDPS、DCBN、BPS、BPの量を変更した他は実施例1と同様にしてイオン交換膜を作製し評価を行った。
BPSの代わりに、2,2−ビス(4−ヒドロキシフェニル)プロパン(略号:BPA)8.0743g(35.37mmol)を用いた他は実施例1と同様にしてイオン交換膜を作製し評価を行った。
BPSの代わりに、2,2−ビス(4−ヒドロキシフェニル)ヘキサフルオロプロパン(略号:BPF)11.8919g(35.37mmol)を用いた他は実施例1と同様にしてイオン交換膜を作製し評価を行った。
各モノマーのモル比を変更した他は、実施例1と同様にしてイオン交換膜を作製し評価を行った。
BPSの代わりに、1,1−ビス(4−ヒドロキシフェニル)シクロヘキサン(略号:BPH)9.4915g(35.37mmol)を用いた他は実施例1と同様にしてイオン交換膜を作製し評価を行った。
