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. Copyright 1999 Academic Press.
