Abstract

Dielectric and enthalpic relaxation times have been measured as a function of composition and temperature. A fractional exponential (W–W) distribution of relaxation times fits both the dielectric and enthalpic relaxation times with different values which are a function of composition. Free volume parameters calculated using the WLF equation are not simple functions of the composition. Concentration fluctuations are considered to be important in these phenomena.
