    • There is provided a method for continuous production of a functional membrane whereby a functional membrane in which a functional polymer is filled into the micropores of a porous resin sheet can be obtained both continuously and efficiently.The method for continuous production of a functional membrane of the present invention comprises a step for impregnating and depositing a polymer precursor (2-acrylamido-2-methylpropane sulfonic acid or the like) having a functional group on a continuously conveyed porous resin sheet (a porous polyethylene sheet or the like); a polymerization step for continuously feeding and bringing into contact first and second resin films (both films comprising polyester films or the like) to one side and the other side, respectively, of the precursor-impregnated/deposited sheet comprising the porous resin sheet into which the polymer precursor is impregnated and deposited, and polymerizing (by irradiation with active energy rays, or by another method) the polymer precursor in a state in which the sheet is sandwiched between the two resin films; a film peeling step; and a polymer removal step.
    • 提供连续制造功能膜的方法,由此可以连续有效地获得功能性聚合物填充到多孔树脂片的微孔中的功能膜。 连续制造本发明的功能膜的方法包括在连续输送的多孔树脂片(a)上浸渍并沉积具有官能团的聚合物前体(2-丙烯酰氨基-2-甲基丙烷磺酸等) 多孔聚乙烯片等); 聚合步骤,用于分别连续进料并将包含多孔树脂片的前体浸渍沉积片的第一和第二树脂膜(包括聚酯膜等的两个膜)分别接触到一侧和另一侧,其中 聚合物前体被浸渍和沉积,并且在片材夹在两个树脂膜之间的状态下聚合(通过用活性能量射线或通过另一种方法照射)聚合物前体; 薄膜剥离步骤; 和聚合物去除步骤。
