Abstract
Polyacrylamide, agarose, and silica gels have been prepared with solvents which are nearcritical binary liquid mixtures. Near the critical temperature of the free liquid mixtures, the binary-liquid gel exhibits a broad region wherein light-scattering intensity is large and varies monotonically with temperature. Some features of this scattering suggest that the gel matrix acts like a random field. Only very weak temporal fluctuations are observed throughout this broad transition region.Keywords
