摘要：
The morphology and crystallinity of plastics articles are influenced by several parameters, in particular the pressure and the temperature history during solidification In this study, the crystallization kinetics and the PVT behavior of a high-density and linear low-density polyethylene resins were evaluated and compared using a high-pressure dilatometer under both isothermal and isobaric conditions. Also, the PVT behavior was compared to the predictions of the Tait equation of state. It was found that the induction time increases with increasing pressure, suggesting that pressure delays crystallization.
