Abstract

A new dynamic model for glass-forming liquids is proposed. It emerges from static and dynamic light scattering data, which show that “glassy clusters” coexist with “fluid regions” in the liquid. The thermodynamic potentials are analyzed in terms of the heterophase fluctuation model. The α-relaxation process is thermally activated and the activation energy for the transformation from the solid to the fluid state is proportional to the solid fraction and to the size of cooperatively rearranging regions. This model yields good agreement with the observed temperature dependence of viscosities and dielectric relaxation rates.
