电解用氟系阳离子交换膜及其制造方法
摘要：
电解用阳离子交换膜，包含具有离子交换基的含氟聚合物和多孔性基材，其特征在于，在该膜的阳极一侧表面具有突出部分，该突出部分包含具有离子交换基的聚合物，在将从该膜的阳极一侧表面到该突出部分的顶点的高度的平均值设为h(μm)时，20≤h≤150，在将该突出部分的分布密度设为P(个/cm2)时，50≤P≤1200，在将该突出部分的与该膜的阳极一侧表面处于同一平面上的底面部的面积分数的平均值设为S(cm2/cm2)时，0.001≤S≤0.6，在将该膜的阳极一侧表面的该突出部分的顶点部的面积分数的平均值设为T(cm2/cm2)时，T≤0.05。
摘要（英）：

A cation-exchange membrane for electrolysis which comprises a fluoropolymer having ion-exchange groups and a porous base. It is characterized by having, on the anode-side surface of the membrane, protrusions comprising a polymer having ion-exchange groups. It is further characterized in that: when the average value of the heights of the tops of the protrusions from the anode-side surface of the membrane is expressed as h ([mu]m), then 20=h=150; when the density of the protrusions distributed is expressed as P (protrusions per cm<2>), then 50=P=1,200; when the average proportion of the areas of those bottom parts of the protrusions which are on the same level as the anode-side surface of the membrane to the area of the anode-side surface of the membrane is expressed as S (cm<2>/cm<2>), then 0.001=S=0.6; and when the average proportion of the areas of the top parts of the protrusions to the area of the anode-side surface of the membrane is expressed as T (cm<2>/cm<2>), then T<=0.05.
