Abstract:

The influence of pressure and temperature on a selection of physical/thermodynamic properties is explored. In the first part, some experimental facts of the thermal behaviour are summarized. The equations of state of melts and glassy amorphous polymers are considered. From this, the pressure dependence of the glass transition temperature is derived.
