2. PvT data for some polymers used in industry

We have selected a number of polymers widely used in industry and, for each of them, we have tabulated specific volumes (in cm ³ · g ^–1 ) as a function of temperature (in K) and pressure (in MPa). For these polymers, some specific data have been compiled that take account almost essentially of the experimental conditions of the measurement, where available. Here again, very different values of specific volume can be observed for the same polymer, depending on its origin and processing, if molar masses or additives are different, for example.
