<P>PROBLEM TO BE SOLVED: To provide: a microporous crystalline polymer membrane that has excellent water resistance and ion adsorption capacity, is highly hydrophilic, has a long filtration life, and has an excellent permeation flow rate; a production method for the microporous crystalline polymer membrane capable of producing the microporous crystalline polymer membrane efficiently; and a filtration filter using the microporous crystalline polymer membrane. <P>SOLUTION: In the microporous crystalline polymer membrane with an asymmetric pore structure, at least a portion of an exposed surface of the microporous crystalline polymer membrane is covered with a radical polymer obtained by polymerizing a composition comprising a radical-polymerizable monomer, a functional compound comprising at least one of an ion-exchanging group or a chelating group has undergone an addition reaction with at least a portion of the radical polymer, and the radical-polymerizable monomer is at least one selected from acrylate, methacrylate, acrylamide and derivatives thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
