We report a real-time, two-dimensional light scattering study of the e
volution of structure in a two-component nonionic micelle system under
going phase separation. We find that the structure of the domains is q
ualitatively similar to that observed in binary fluid systems, with so
me anomalies observed. However, compared to the Lifshitz-Slyozov predi
ction for simple binary fluids, the domain growth is unexpectedly slow
. In fact, the growth kinetics can be empirically described as a stret
ched exponential approach to a pinned domain size. This anomalous beha
vior may be due to the ability of the spherical micelles to reorganize
into more complex structures.
