ABSTRACT Early stages of phase separation in liquid mixtures of polystyrene (PS) and poly(methylphenylsiloxane) were studied by light scattering. Measurements were made at four concentrations less than 60 wt% PS and at several temperatures in the two-phase region. The time (_t_) dependence of maximum intensity of scattered light _I_m and the corresponding wave number _k_m did not obey the Cahn theory but could be represented by power-laws: _I_m∝_t_θ and _k_m∝_t_φ with θ=0.69 (±0.17) and φ=−0.29 (±0.05). These values of θ and φ agree well with those predicted by recent theories of Langer _et al._ and Binder _et al._ for spinodal decomposition, and also with the experimental values for binary mixtures of small molecules. It was concluded that there is no essential difference in the mechanism of phase separation between mixtures of small molecules and polymer blends.
