Abstract
The dynamics of phase separation has been investigated by light scattering measurements with a critical liquid mixture of polydimethylsiloxane in diethyl carbonate. It is found that the structure factor has a scaling form predicted by recent theories. The experimental result suggests that the negative diffusivity is dependent on the wave number in the unstable region of the phase diagram.Keywords
