✦ Synopsis

The dispersion force component of surface free energy, rg, and the nondispersive interaction free energy between solid and water, Iiw, were determined by the two-liquid contact-angle method, i.e., by the measurement of contact angles of water drops on plain solids in hydrocarbon, for commercially available organic polymers such as nylons, halogenated vinyl polymers, polyesters, etc. A method to estimate the I$, values from the knowledge of the polymer composition is also proposed, on the basis of the assumption of the spherical monomer unit and the s u m of interactions between functional groups and water molecules at the surface.
