Tricontinuous structure in a homopolymer–homopolymer–random-copolymer ternary mixture quenched under the tricritical point

We proposed a dynamical method to simulate the time change in the domain structure for a homopolymer–homopolymer–random-copolymer ternary mixture quenched under its tricritical point. The system studied underwent a phase separation into tricontinuous domain structure. The growth of the domain structure obeys a ${\mathit{t}}^{\mathrm{-}1/3}$ power law and the dynamical scaling law is valid in the late stage of phase separation.
