摘要：

Rubber swelling theory is revisited in an attempt to derive consistent thermodynamic expressions for the elastic free energy valid for the swelling of a crosslinked polymer by liquids, gases or supercritical fluids. In this approach, evaluation of solvent properties in a hypothetical reference state is not needed. An equation of state for the crosslinked polymer is presented which may be used for the evaluation of its internal pressure. Model calculations are compared with experimental data on the swelling of crosslinked poly(dimethylsiloxane) by benzene and supercritical carbon dioxide.
