Description
本発明の方法に従って処理できる逆浸透膜は、ポリアシルハライド、ポリスルホニルハライド又はポリイソシアネートとポリアミン又はビスフェノールとの反応生成物を含んでいる。この反応生成物は、通例、多孔質支持裏材の内部及び/又は表面上に付着している。
本発明の従えば、逆浸透膜(例えば、上述のようにして製造した膜)が約1秒〜約24時間の範囲内の時間にわたって硝酸ジプロピルアンモニウム、硝酸ジイソプロピルエチルアンモニウム、硝酸トリエチルアンモニウム、硝酸テトラエチルアンモニウム、硝酸ジエチルアンモニウム又はホウ酸テトラエチルアンモニウム或いはこれらの混合物に暴露される。膜の暴露は、通常、周囲温度から約90℃以上までの範囲内の温度、好ましくは約20〜約40℃の範囲内の温度で行われる。
