Abstract
Abstract Dynamic visco-elastic behaviors of the aluminum stearate nujol system were studied, using a concentric cylinder type forced oscillation rheometer. The system behaves always as a typical visco-elastic body in a wide range of concentrations and temperatures, and manifests conspicuous amplitude and frequency dependence, which indicates non-linear visco-elastic properties. Wedge type relaxation spectra of the system were obtained, and it was found that the system is thermo-rheologically simple in a confined region of temperatures. The time effect of the specimen and temperature dependence of dynamic properties were examined, and the rheological structures in the system under various conditions were discussed.
