The phase separation process of polystyrene (PS) /poly (metylphenylsiloxane) (PMPS) liquid mixtures was investigated by light scattering. In order to test the scaling law S (k, t) =km-3s (k/km), which represents the self-similarity of the phase structure, we tried to superpose the measured structure function S (k, t) . Here k is the wave nunber, km the wave number yielding the maximum intensity and s (k/km) the scaled structure function independent of time t. The superposition for the critical composition was fairly good. However, S (k, t) for off-critical compositions gradually changed with t, coming to have a broader peak, so that the superposition was not so good. The observed exponent describing the wave number dependence at k>km was near the one given by Porod's law, i. e., -4, for both the critical and off-critical compositions. However, the conservation law ∫∞0 [k4s (k, t) -2πA] dk=0 proposed by Tomita, qualitatively held only for off-critical compositions.
