Lattice-hole theory: Bulk properties and surface tension of oligomers and polymers

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 species, typified by n-alkanes. Successful results for surface tension and its temperature coefficient ensue. As to further applications to high polymers, a satisfactory outcome is obtained for absolute values and temperature coefficients in the majority of the numerous instances of structurally diverse systems. This encourages predictions for some high T-g,systems, and mixtures, where experimental information is not available. (C) 1999 Academic Press.
