## Abstract The pressure–volume–temperature (__PVT__) dependencies of several amorphous polymers (PS, PC, PPE, and PPE/PS 1:1 blend) in the glassy and molten state were studied. The Simha–Somcynsky (__S__–S) lattice‐hole equation of state (EOS) was used. Fitting the __PVT__ data in the molten state
## Abstract In a plasticating extruder, solid polymers are heated and are subjected to high pressures before they are melted and delivered to a die. In both the solids conveying and melting sections, these temperature and pressure increases will compact the unmelted polymer bed as it moves down the
