摘要：

Contact angle measurements with three different liquids were performed on: (i) butyl rubber PB 101-3 (Polysar Ltd.) and (ii) Dow Corning 236 dispersion. Contact angles were measured at different temperatures within the range from 23-degrees-C (room temperature) to 120-degrees-C. The surface tensions, gamma-SV, of the polymeric coatings at each temperature were calculated from the contact angles. The temperature coefficients of the surface tensions, d-gamma-SV/dT, i.e., the surface entropies, were established for the temperature range covered.
