A new method to observe a pressure-glassification of polymers by using a high pressure d.t.a, is proposed. Pressure scanning, instead of the usual temperature scanning, gave a d.t.a, curve typical of the glass transition. The glass transition pressure at a constant temperature for polystyrene was determined and analysed.
