The effect of pressure on the processing and, in particular, on the crystallization kinetics of a polymeric material, is often ignored because of the difficulties involved in the experimental measurements. As a consequence, crystallization behaviors were rarely described by using a model which takes into account the effect of pressure on the crystallization [1, 2]. In this study, experimental data on the dependence of the specific volume on temperature and pressure of isotactic polypropylene using a high-pressure dilatometer up to 150 MPa are reported and discussed.
