Description
(1)発明の分野
本発明は、概略的には、ポリアミド膜に関し、修飾剤(例えば、これらに限定するものではないが、所定のオキサゾリン系および/またはチアゾリン系の化合物、その誘導体およびポリマー等)の適用によってこのような膜を修飾する方法を包含する。
ポリアミド膜は、流体の分離を行なうために何十年もの間使用されてきた。このような膜の古典的な例は、FilmTec CorporationのFT−30(商標)膜であり、これは、薄いフィルムのポリアミド層を有するマイクロ多孔質ポリスルホンシートを含む。米国特許第4,277,344号および第5,658,460号(Cadotteら);米国特許第6,878,278号(Mickols);米国特許第6,024,873号(Hirose)および米国特許第4,950,404号(Chau)に記載されるように、ポリアミド層は、多官能アミンモノマーと多官能アシルハライドモノマーとの界面重縮合反応によって得られる。このようなポリアミド膜を修飾する方法は、米国特許第5,876,602号(Jonsら);米国特許第5,755,964号および米国特許第6,280,853号(Mickols);米国特許第4,888,116号;米国特許第4,765,897号;米国特許第4,964,998号(Cadotteら);米国出願公開第2007/0251883号(Niu);米国特許第5,178,766号(Ikedaら)および米国特許第6,913,694号および米国出願公開第2007/0175821号(Kooら)に記載されている。先の文献の各々の全内容は、完全に本明細書に組入れる。ポリアミド膜を修飾するための更に他の方法が、国際公開第WO2007/133362号パンフレット(Mickolsら)に記載されている。
本発明は、修飾ポリアミド膜ならびにその製造方法および使用方法を包含する。本発明は、ポリアミド膜を所定の修飾剤(例えば、これらに限定するものではないが所定のオキサゾリン系および/またはチアゾリン系の化合物、その誘導体およびポリマー)と接触させることを含む方法を包含する多くの態様を包含する。好ましい態様は、改善された性能、例えば所定の種(例えば、塩化ナトリウムおよび/またはホウ酸)の拒絶の増大、汚染の低減、抗微生物特性の増大、および/または貯蔵安定性の改善を示す。多くの追加的な態様、目的、利点および特徴が開示される。
本発明は、ポリアミド膜または適用の具体的な種類、構造または形状に特に限定するものではない。すなわち、本発明は、種々の用途,例えば逆浸透(RO)、ナノろ過(NF)、限外ろ過(UF)、およびマイクロろ過(MF)流体分離に用いられる、平坦シート、チューブ状および中空繊維のポリアミド膜に適用可能である。しかし、本発明は、コンポジットポリアミド膜,例えば背景技術の項で前記したようなものを修飾するために特に有用である。これらの種類のコンポジット膜は、一般的に、マイクロ多孔質支持体および「薄フィルム」ポリアミド層を含む平坦シートとして提供される。このようなコンポジットポリアミド膜は、ROおよびNF分離用のらせん巻モジュールに最も一般的に使用される。
開始:
