Abstract

We present detailed comparisons of results on the late stage dynamics of spinodal decomposition obtained by the computer simulation of the time-dependent Ginzburg-Landau equation with hydrodynamic interaction and experiments of a polymer mixture of polybutadiene and polyisoprene. We show that the temporally linear domain growth law, which is characteristic for viscous fluids, is observed in both simulation and experiment in the late stage. Some quantities obtained in such a hydrodynamic domain growth region, such as the interface area density and the scaling function, are compared in detail. Especially, we show that the scaling functions for the two systems are in quantitative agreement.
