The gelation process of the polyacrylamide hydrogel is investigated. Some properties of the solvent in gels are verysimilar to those of the solvent in free solution,but some properties are not. The author is interested in the similaritiesand the differences between these two states,gel and solution,and have investigated some properties of gels and pre-gelsolutions. When the molecular structures of polyacrylamide hydrogels during gelation reaction were investigated bymeans of Raman scattering, the change of intensity not owing to the molecular structure was observed. The authorinvestigates the intensity changes of Rayleigh scattering light which may occur during the gelation process. He-Nelaser, Ar⁺ ion laser, or halogen lamp are used as the light source, and the scattering light is monitored by the smallspectrophotometer with CCD. The intensity of scattering light increases abruptly after some duration time. It issuggested that the abrupt increase coincides with the gelation or polymer network formation. The intensity ofRayleigh scattering light increases abruptly owing to the abrupt change of the microstructure of the solution.
