Summary The dynamics of spinodal decomposition (SD) after a temperature jump from a kinetically formed single phase state into the unstable part of the two-phase region has been studied with a blend of polystyrene and poly(cyclohexyl acrylate-statbutyl methacrylate). The time evolution of the structure factor has been examined by small-angle neutron and light-scattering techniques. The combination of the different techniques gave access to a wide wave vector and time range covering a large range of length scales. The activation energy of the diffusion process during spinodal decomposition was determined by a scaling analysis of the later stages of SD, because early stages of SD could not be resolved.
