Abstract
The composition dependence of the glass transition temperature Tg was studied using differential scanning calorimetry for three different ty pes of binary mixtures. The fit of the Tg curves versus composition wi th equilibrium thermodynamic equations has led to good agreement betwe en experimental and theoretical curves. This surprising result was dis cussed in terms of molecular organizations in the glassy state.
