Alkaline stability (1 M KOH, 60 0C for 168 h): OH- conductivity reduced 30-34% : weight loss of the membranes 2-5%
10
Alkaline stability (1 M KOH, 60 0C for 1400 h): OH-
ion conductivity reduced 19-26%
11
Stability :the conductivity, IEC and mechanical property values remained almost unchanged (2.5 M KOH at 60 0C for about 3000 h)
