β¦ Synopsis
a boundary condition through which it is given by a bulk A cell theory for the prediction of the surface tension of simple datum ( 5 ) . This changes the cell theory calculation of s liquids is modified to account correctly for the fractional change to one which requires that only bulk properties be fit. This in the potential energy zero term due to missing nearest neighbors calculation thus affords a more predictive measure of s of order greater than one. A measure of the surface width is oband a more critical comparison of the results of the cell tained directly from bulk data. Theory and experiment are in theory with experimental data than has been possible pregood agreement without any adjustable surface parameters.

A scheme for the prediction of surface tension from bulk properties of polymer melts was previously developed. It is based on a combination of Guggenheim's empirical temperature function with a hole or free volume fraction, derived in lattice-hole theory. This approach is now extended to oligomeric
