実施例
実施例1:HFA−MDAポリアミドの製造及び性能
膜の調製:HFA−MDAポリアミド複合膜を、前もって作られたポリスルホン(PSF)限外濾過膜上に、界面合成した。塩基性水溶液中に溶解した「イオン化したHFA−ジアミン単量体」の被覆を増加させるために、界面重合の前に、前記PSF支持膜に40秒間、UV−オゾン処理を行った。上記のとおりに前処理したPSF膜を、5分間、2%(w/v)HFA−MDAジアミン(上記の反応1中の単量体1)塩基性水溶液中に入れ、それから、余分な溶液を除くために、HFA−MDAに浸漬した支持膜上でゴムローラーを回転させた。
実施例2:HFA−ODAポリアミドの製造及び性能
実施例1で記述された条件と同じ条件の下で、2%(w/v)HFA−ODAジアミン(反応1における単量体2)とTMCから、HFA−ODAポリアミド複合膜を調製した。
実施例3:モデルポリアミド重合体を使用した耐塩素性テスト
モデル重合体、HFA−MDAポリアミドの合成:窒素の導入及び排出管を付けた100ml三つ口フラスコに、HFA−MDAジアミン(1.50g)とDMAc(8ml)を加えた。溶液にした後、フラスコをドライアイス/アセトン浴に浸けた。溶液を凍結させた後、塩化イソフタロイル(0.57g)とDMAc(2ml)を加え、それから、機械式攪拌機を使って、窒素を通しながら氷/水浴中で3時間、さらに、窒素を通しながら室温で20時間、混合物を攪拌した。メタノール中での析出後、ろ過及び60℃での減圧乾燥によって重合体(1.87g、Mw(Mw/Mn)=118,000(1.67))を得た。
