Abstract: | Summary Analysis of reported data on the swelling and deformation of polymer networks shows that the volume-dependent term in the deformational free energy cannot be neglected. The analysis is based on a comparison between the equilibrium modulof networks prepared at various dilutions and of the same degree of swelling and on a comparison between concentration dependences of the interaction parameter for a linear and a crosslinked polymer. |
