Document Type and Number:
Japanese Patent JP2018167134
Kind Code:
A
Abstract:
To provide a polymer functional membrane which has low membrane resistance and excellent pH resistance, and a module and an apparatus having the polymer functional membrane.SOLUTION: A polymer functional membrane contains a polymer compound, where the polymer compound is a polymer compound obtained by curing a composition containing, in one molecule, two or more α-alkyl acryloylamino group or α-alkyl acryloyloxy group and a polyfunctional polymer having an ionic group, and when the ionic group is a cationic group, a CLogP value of the polyfunctional monomer is -5.2 or more, when the ionic group is an anionic group, the CLogP value of the polyfunctional monomer is -1.9 or more, and a content of the polyfunctional monomer with respect to the total mass after drying is 500 ppm or more and 3,000 ppm or less.SELECTED DRAWING: None
