Pressure-Volume-Temperature (PVT) properties of polymers are very important data for polymer processing, especially, injection molding. The coefficients of thermal expansion in polymers are much larger than those of metals and inorganic materials. So the changing of specific volumes in polymers is very large under processing, i. e., for changes of temperature and pressure. In this paper we describe the relationship between PVT behavior and processing in polymers.
