The dynamic behavior of water within two types of ionomer membranes, Nafion and sulfonated polyimides, has been investigated by field-cycling nuclear magnetic relaxation. This technique, applied to materials prepared at different hydration levels, allows to probe the proton motion on a time scale of

## Abstract The water dynamics of two types of ionomer membranes, the Nafion^ยฎ^ and sulfonated polyimides, have been investigated by fieldโcycling nuclear magnetic relaxation. This technique, applied to samples prepared at different water content, allows to characterize the proton motion at the tim
## Abstract **Summary:** The molecular dynamics of polymer melts with molecular weights above their critical values have been described by a power law dependence of the spinโlattice relaxation time on the Larmor frequency. Three different regimes of power laws describing the relaxation dispersion o
