Abstract

We investigated structure and viscoelasticity of alminium stearate in non-polar solvent of decalin. Alminium stearate formed thread-like linear aggregate in decaline and showed a viscoelastic behavior of transient network. Its viscoelastic behevior and structure changed at around 55°C. In high temperature region above 55°C, G″ showed clear minimum and G′ and G″ could be superposed on master curves by time-temperature conversion scheme. Below 60°C, however, G″ did not shows a clear minimum and G″ could not be superposed on a master curve in high frequency region. Small neutron scattering measurement showed that the linear aggregate had a longer correlation length and a larger thread diameter in high temperature region than in low temperature region.
