Abstract

Swelling and scattering measurements are reported from chemically cross‐linked polyvinyl alcohol) hydrogels and the corresponding semi‐dilute polymer solutions. The mixing free energy in the swollen network is found to be significantly smaller than that of the corresponding polymer solution at identical concentration. Static light scattering and small‐angle neutron scattering measurements indicate the presence of large‐scale static structures in the solution. Reasonable agreement is found between the osmotic moduli obtained from light scattering measurements and macroscopic osmotic observations.
