Abstract
An extension of the normal Gibbs formulation of statistical mechanics is applied to gels with
permenent cross-links. The formalism permits an evaluation of the free energy in the case where the gel is
dense, taking full account of excluded volume. This theory yields the changes in osmotic pressure upon
cross-linkage and allows fully for syneresis; it enables the full elasticity of the network to be calculated, including
the bulk modulus. Corrections to the simple addition of the free energy terms from network and solution
theories are obtained, and for the case of a network in equilibrium with pure solvent a particularly simple
formula is found.
