WebVarious organic molecules, in particular polymers, are extremely good glass formers and allow the study of supercooled melts near the glass transition in metastable equilibrium Theories of the glass transition imply such an equilibrium (eg mode-coupling theory, or Gibbs-di Marzio theory) and can hence be tested in these systems Simplified lattice … WebGlass Transition Temperature Glass Transition Temperature (Tg) is the point at which a material changes from its “glass-like” state into a more flexible, rubbery, elastic compound. Historically, Differential Scanning Calorimetry (DSC) was used. DSC, however, does not measure a discreet point but a “thermal event” over a temperature range.
