Document Type and Number:
Japanese Patent JP2017023927
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ion adsorption filter having excellent ion adsorption property and organic solvent resistance at high temperature.SOLUTION: An ion adsorption filter having a modified polyolefin resin on a surface of a porous substrate is provided in which: the modified polyolefin resin is composed of a polyolefin copolymer containing an olefin hydrocarbon unit and an N-substituted imide unit derived from an unsaturated carboxylic acid anhydride unit; and an N-substituent in the N-substituted imide unit derived from the unsaturated carboxylic acid anhydride unit is a substituent represented by the following (I) or (II). -(CH)NRR(I) -(CH)NRRRX(II), where Rand Rrepresent an alkyl group having 1 to 5 carbon atoms, a hydroxyalkyl group having 1 to 5 carbon atoms, Rrepresents a residue of a quaternization agent introduced by a quaternization reaction or hydrogen, Xrepresents an anionic counter ion and n represents an integer of 1 to 5.SELECTED DRAWING: None
