摘要：

The critical dynamics of a moderately-high-molecular-weight polymer blend of polystyrene and polybutadiene diluted in dioctyl phthalate is studied near the consolute point by dynamic light scattering. Fast and slow modes are observed as in previous experiments on a low-molecular-weight binary-polymer-blend melt. The light-scattering data are consistent with a Fisher renormalization of the correlation-length exponent.
