  A dynamical lattice model is used to study the viscosity and the
velocity-velocity autocorrelation function in a microemulsion phase. We find
evidence of anomalous viscosities in these phases (relative to water-rich
and/or oil-rich phases), in qualitative agreement with other results. We also
investigate the dynamic relaxation in the microemulsion phase. It has been
suggested that the temporal relaxation in the microemulsion phase may be
described by a stretched exponential Kolrausch-Williams-Watts law. In our
model, we find the velocity-velocity autocorrelation function fits this law,
showing both enhanced (b>1) and inhibited (b<1) diffusion.
