The generalized two-dimensional correlation analysis based on time-resolved light scattering patterns(2D TRLS)has been employed to study the phase separation process of an epoxy-amine-polyethersulfone blend in which the secondary phase separation takes place.The results of the 2D TRLS provided more detailed information that was not readily observed in the 1D TRLS patterns.(ⅰ)During the first process of phase separation,the sequential order of coarsening in size of the domains among the larger and smaller ones has been reversed between the diffusion regime and the hydrodynamic regime.(ⅱ)The change of the larger domains in size,due to the hydrodynamic flow in the late stage of the first phase separation process,keeps on taking place earlier than that of the new domains appeared in the secondary phase separation process.(ⅲ)During the secondary phase separation process the size growth of the smaller domains takes place earlier than that of the larger ones,probably due to the assumption that the coarsening mode could decrease the interface tension more quickly.
