説明

The collective diffusion coefficients, Dc, in polyacrylamide gels having the same network structure were measured as a function of volume fraction of polymer in gel with a dynamic light scattering method. In order to prepare the gels with different volume fractions of polymer, the gel samples were first produced under the same conditions and then swelled or shrunk by immersing in methanol or acetone-water solutions. The value of Dc decreased with the increase of the concentration of methanol (acetone) in the solvent; however, it then approached a constant value at a concentration near where the viscosity of the solvent is a maximum.
