Abstract

The derivation of an equation which describes the temperature dependence of relaxation behavior in equilibrium supercooled liquids in the vicinity of the glass transition is presented. The view that the glass transition can be treated in terms of the theory of second-order phase transitions is used, in conjunction with the identification of the "driving force" for molecular cooperative rearrangements in terms of fluctuations in certain thermodynamic variables, toward a calculation of how these fluctuations relate to relaxation behavior in liquids. The relation of the derived equation to the Adam-Gibbs equation and to the empirical WLF or Fulcher equation is also discussed.
