✦ Synopsis

According to the theory of Frenkel. surface energy, viscosity and droplet size are the factors which determine the coalescence kinetics of two identical spherical droplets (spherules) which are in contact. From the Frenkel relationship and observations of mesophase spherule coalescence kinetics, we have evaluated the mesophase/isotropic interfacial energy for a mesophase-containing pitch. The interfacial energy is quite small (< 1 dyne/cm) in agreement with a prediction of White.
