Vollmer] The kinetics of phase separation is studied for a droplet-phase microemulsion, where the phase separation is induced by constant heating. In that case the droplets shrink in a stepwise manner at the expense of a growing water-rich phase. The parameter dependence of the height of the energy barrier preventing this phase separation is discussed, and a general argument for the stepwise decrease in the droplet size is presented, which provides a quantitative description of microcalorimetric data. Finally, a superimposed structure on the signal of the apparent specific heat is explained by an argument which underlines the importance of the conservation of volume and of interfacial area for the modeling of this explicitly time-dependent kinetics.
