Hello!

I am looking for some hints on how to estimate the kinetics of phase separation in a mixture.

I regard a ternary immiscible blend of two polymers A and B in a common solvent C. The phase diagram of this ternary system has a binodal line and a spinodal line, and if I start inside the unstable region, the system eventually falls into two phases enriched by A and B. If the viscosity is high, this phase separation process takes more time. How could I extimate the typical kinetics of this phase separation?

I've heard of Cahn, Hilliard and Cook theory, but I am not sure if it is applicable. I can't get the idea of how to estimate the time of transition from a metastable state (let's say, prepared by intense mixing) to an equilibrium state. Could you please help me?
