The spinodal decomposition (SD) of the homopolymer blends has been studied by the numerical integration of the Cahn-Hilliard-Cook equation with the Flory-Huggins-de Gennes free energy functional. The scaling dependences for the surface area density, Euler characteristics density, average Gaussian and mean curvatures of the blend interface have been found. In the shallow and asymmetric quenches the topological transformation from the bicontinuous to droplet morphology has been observed. The influence of the thermal fluctuations on the curvature distribution has been investigated.
