摘要：

We report the effects of long-range correlation for a critical mixture of polystyrene (Mn≈392000) in cyclohexane at small temperature distances from the phase separation temperature (T-Tp< 1.5°) by means of quasielastic light scattering. The estimated coherence length for the polystyrene-cyclohexane system from Rayleigh linewidth studies is somewhat smaller than that from angular dissymmetry measurements if we assume that the temperature dependence of the molecular-interaction range remains unchanged from static to dynamic phenomena.
