Description

（１）スルホン化度（置換度）
精製、乾燥後のスルホン化ポリエーテルスルホンを重水素化ジメチルスルホキシドに溶解し、600MHz H-NMR（BRUKER AVANCE 600）より測定した。1H-NMRスペクトルで得られた芳香環水素のピーク積分値及び下式より、スルホン化度（置換度）を算出した。
スルホン化度（置換度）
=[8.2〜8.5ppmの積分値(下記化学式中の(1))]/{([6.8〜8.2ppmの積分値(下記化学式中の(2)〜(5))]-[8.2〜8.5ppmの積分値]×2)/4+[8.2〜8.5ppmの積分値]｝ (1) Sulfonation degree (substitution degree)
The sulfonated polyethersulfone after purification and drying was dissolved in deuterated dimethylsulfoxide and measured by 600 MHz H-NMR (BRUKER AVANCE 600). Peak integrated value of aromatic hydrogen obtained in IH-NMR spectrum and Ri by the following equation was calculated degree of sulfonation (degree of substitution).
Sulfonation degree (substitution degree )
= [ Integrated value of 8.2 to 8.5 ppm ((1) in the following chemical formula ) ] / { ([Integrated value of 6.8 to 8.2 ppm ((2) to (5) in the following chemical formula )]-[8.2 to 8.5 ppm Integral value] × 2 ) / 4 + [8.2 to 8.5 ppm integral value] }
