Abstract

Small angle scattering techniques reveal structural differences between polymer solutions and gels. In the present work the macroscopic thermodynamic response of permanently cross-linked network systems swollen in good solvents are investigated and compared with the results obtained from small angle neutron scattering measurements. The results demonstrate that the macroscopic thermodynamic properties of the swollen polymer networks investigated here are satisfactorily described by a free energy function containing a separable elastic and mixing contribution. The neutron scattering signal of the gels can be decomposed for a solution-like and a static part. The swelling pressure derived from the solution-like component of the gel spectra is in reasonable agreement with that obtained from macroscopic osmotic measurements.
