The composition dependence of the glass transition temperature T sub G and the composition dependence of supercooled liquid transport properties for binary mixtures and derived from the viewpoint of the configurational entropy theory of glassification. Theoretical expressions can be evaluated with available thermodynamic data. These derived relations are shown to reduce to the empirical equations which describe the composition dependence of T sub g and of supercoooled liquid transport properties, and the empirical adjustable parameters are identified with physically meaningful quantities. An equation for the composition dependence of T sub g is compared with experimental data from binary mixtures with satisfactory agreement.
