Formation temperature of ultra-stable glasses and application to ethylbenzene

- The driving force of the glass transition at Tg is an enthalpy saving.
- A frozen enthalpy excess induces liquid and stable glass phases.
- The ultra-stable glass is formed at the structural relaxation enthalpy maximum.
- The ultra-stable phase occurs in many glasses at the Kauzmann temperature TK.
- The enthalpy saving maximum is predicted above TK for ethylbenzene.
