Abstract—Polarizing microscopy was used to study the kinetics of formation and droplet size growth of the
ordered (nematic) phase during the phase separation of an azomethine dimer melt at various rates of cooling.
The statistical droplet size distribution of the nematic phase during phase separation was described by a model
derived in terms of the thermodynamics of irreversible processes. Two kinetic phase separation stages were
observed and described by the universal scaling function.
