A corresponding states principle is demonstrated for polymer and oligomer liquids. Scaling the measured surface tension with the thermodynamic properties obtained from pressure, volume, and temperature data, one obtains a universal curve. A strict adherence to the corresponding states principle is observed within each oligomer to polymer homologous series. This allows model`s based on equation of state theories to predict the surface tension to within 1% accuracy for such a homologous series. The existence of a strict corresponding states principle implies that for the polymers studied by us, the dominant contribution to the surface tension comes from the cohesive and entropic properties of the bulk liquids. The implications of the corresponding states principle to the prediction of the surface and interfacial tension in polymer melts is outlined.
