✦ Synopsis

The dielectric behaviour of an aqueous solution-in-oil emulsion in which the liquid within the particles forms a glassy structure on being taken below its glass transition temperature is reported. Measurements have been made for a single concentration of oil/solution/surfactant which gave a stable emulsion structure over the temperature range 225-340 K, indicating a glass transition at 218 K. The principal features of the low-frequency dielectric response are considered in terms of the model response discussed earlier by the authors and the physical bases of the individual response components are established.
