polymers from iSAFT. The pure component parameters used to calculate the surface
tension of these real components were regressed to their bulk phase behavior. The
study clearly demonstrates that both bulk phase behavior and interfacial properties
can be described within the single framework of iSAFT (with the same set of pa-
rameters for both the systems). The success of the theory motivates us to extend
it to more complex systems, like copolymers and polymer brushes. However, few
shortcomings in iSAFT prevent us from doing so.

The approximations in iSAFT are most accurate for the average segment density of
homonuclear polymers. If the segments on the polymer are too dissimilar, the theory
becomes less accurate. Even for homonuclear polymers, iSAFT does not constrain
