Abstract
The contribution group method consists of attributing to each chemical group of a molecule or a macromolecule a contribution to the Hamaker constant and to the surface free energy. From the Hamaker constants and the surface energies of organic liquids, the contributions of several carbonated groups are determined in order to calculate the surface properties of different polymers. The calculated values of their surface free energies are found to be in fairly good agreement with those obtained either from wettability measurements or by surface tension measurements of molten polymers.
