実施例2で合成したポリマーを比較例1の手法により処理し、茶褐色の沈澱物を回収、80℃、12時間で真空乾燥した。粉末は水溶性でフィルム化できず、粉状態のままであり伝導率測定が不可能だった(イオン交換容量:3.79mmo1/g)。
住友化学製スミカエクセル(3600P)4.00gを50mlナスフラスコ中の発煙硫酸(30wt%)20ml中へ攪拌しながら投入後、60℃に昇温して2時間保持し、室温まで冷却後、-30℃に冷やした関東化学製脱水ジエチルエーテル500ml中へ激しく攪拌しながら滴下した。減圧濾過で沈殿物を回収後、再度脱水ジエチルエーテルと脱水アセトニトリル混合物(体積比8:2)で洗浄し、再度減圧濾過で白色の沈殿物を回収した。これを80℃、12時間で真空乾燥し、純水に溶かした後、平滑なガラス板上にキャストし、乾燥させたまま対向電極にセットして、ESPEC社製恒温槽内へ入れ、80℃、10%RHに12時間保持し、伝導率を測定した。このときの伝導率は1.03×10-6S/cmだった(イオン交換容量:2.61mmo1/g)。
実施例2で得たポリマーを攪拌子入り50ml三口ナスフラスコ(滴下漏斗付)に1g入れ、アルゴン置換してナカライテスク製脱水塩化メチレン20mlを投入し3時間攪拌して均一溶液とした後、-30℃まで冷却した。クロロ硫酸1.17ml(3.0mmo1/g狙い)をナカライテスク製脱水クロロホルムに5wt%で溶解させ、攪拌しながらゆっくり滴下した。滴下中にポリマーは液中で沈澱物として析出した。これを減圧濾過で取り出した後、10wt%水酸化ナトリウム水溶液100mlで洗浄した。純水で十分洗浄した後真空乾燥した。これをナカライテスク製DMAcに15wt%の比率で溶かし、平滑なガラス板ヘキャストした後に1N塩酸で酸処理した結果、黄色の透明なフィルムを得た。これを対向電極にセットして、ESPEC社製恒温槽内へ入れ、80℃、10%RHに12時間保持し伝導率を測定した。このときの伝導率は9.67×10-7S/cmだった(イオン交換容量:1.96mmo1/g)。
