It had been shown in two‐dimension case that the Chan‐Hilliard‐de‐Gennes model describes the processes of phase separation both in spinodal and metastable regions. The nature of the structures birth different for different regions. It is rigid in metastable regions, while in spinodal regions it may be both rigid and smooth. Analytical expression for the boundaries separating the regions with rigid and smooth birth of the structures is obtained.
