up to 70˚C for membranes with sulphopropyl acrylate
and up to 90˚C for membranes with styrene sulphonate.
Water swelling coefficient was shown to increase line-
arly with the increase of sulphomonomer content. We
were able to obtain membranes with IEC up to 1.4 mg-
equiv/g for membranes with sulphopropyl acrylate and
up to 0.8 mg-equiv/g for membranes with styrene sul-
phonate. This makes the membranes viable for further
research both as ion-exchange membranes or proton-
conducting membranes.
