Understanding the properties of polymeric materials under high pressure is of great importance in polymer processing. This is because high pressure has a large effect on the behavior of the resin (such as flow, crystallization, compatibility, etc. ) during the molding processes, and thus strongly influences the quality of the molded products. In this review, we report on measurements of the various properties of polymeric materials under high pressure which have been recently carried out. Examples include: (1) specific volume of resins under high pressure and rapid cooling rate corresponding to the actual molding conditions. (2) the pressure dependence of thermal conductivity, Young's modules and Poisson's ratio measured by modified PVT apparatus. (3) the pressure dependence of viscosity.
