Description

A simple theory of surface tension γ for polymer liquids is presented with the use of a hole theory of polymer liquids. It is found that if γ(σ3⁄C)2⁄3C⁄ε*z′ is taken as the reduced surface tension the principle of corresponding states is in satisfactory accord with theory, where σ is a characteristic parameter for separation involved in the Lennard-Jones 12-6 potential; ε* is that for potential energy; 3c is the number of external degrees of freedom per segment, and z′ is the average coordination number of a segment. The theory makes it possible to interpret the so-called Hildebrand equation for the relation between γ and cohesive energy density, and shows that the parachor is proportional to the product of the 13/12-th power of an occupied volume σ3N and the 1/4-th power of a characteristic cohesive energy density, 0.69ε*z′/σ3, when an appropriate atomic group is taken.
