Title:
ION-EXCHANGE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2016/133170
Kind Code:
A1
Abstract:
The present invention provides: a (vinyl alcohol)-based ion-exchange membrane having practical dimensional stability and electrodialysis performance; and a process for producing the ion-exchange membrane. The present invention relates to an ion-exchange membrane which gives an infrared absorption spectrum that satisfies the relationship (A): 30≤{Z-(X+Y)×30/2}/T (A) wherein X is the absorbance at an absorption wavelength of 1,690 cm-1, Y is the absorbance at an absorption wavelength of 1,720 cm-1, Z is the integral for the region lying between absorption wavelengths of 1,690 cm-1 and 1,720 cm-1, and T (cm) is the thickness of the ion-exchange membrane.
