Title
(EN) METHOD FOR PRODUCING POROUS MEMBRANE AND POROUS MEMBRANE
(FR) PROCÉDÉ DE PRODUCTION D'UNE MEMBRANE POREUSE ET MEMBRANE POREUSE
(JA) 多孔質膜の製造方法および多孔質膜
Abstract
(EN)
The present invention provides a method for producing a hydrophilic porous membrane that is highly water permeable and resistant to the effects of treatment, e.g., washing, the method comprising preparing, as substrate, a membrane that has a plurality of pores that contains a water-insoluble resin, e.g., polysulfone, and a water-soluble resin containing a monomer unit of polyvinylpyrrolidone or a monomer unit of polyvinyl alcohol; and crosslinking at least a portion of the water-soluble resin by irradiating the substrate with an electron beam in the presence of an aqueous solvent.
(FR)
La présente invention concerne un procédé de production d'une membrane poreuse hydrophile qui est hautement perméable à l'eau et résistante aux effets du traitement, par exemple, lavage, le procédé comprenant la préparation, en tant que substrat, d'une membrane qui a une pluralité de pores qui contiennent une résine insoluble dans l'eau, par exemple, du polysulfone, et une résine soluble dans l'eau contenant une unité monomère de polyvinylpyrrolidone ou une unité monomère d'alcool polyvinylique; et à réticuler au moins une partie de la résine soluble dans l'eau par irradiation du substrat avec un faisceau d'électrons en présence d'un solvant aqueux.
(JA)
本発明により、透水性が高いとともに、洗浄などの処理の影響を受けにくい親水性を有する多孔質膜の製造方法として、基材として、ポリスルホンなどの非水溶性樹脂とポリビニルピロリドンのモノマーユニットまたはポリビニルアルコールのモノマーユニットを含む水溶性樹脂とを含む複数の細孔を有する膜を用意すること、および水性溶剤の存在下で上記基材に電子線照射して上記水溶性樹脂の少なくとも一部を架橋することを含む、上記製造方法が提供される。
