Abstract
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 fo r polystyrene was determined and analysed.
