Description	A method for the determination of pressure-affected viscosity from capillary rheometry and pressure-volume-temperature (PVT) data was tested on polyphenylsulfone melt. Shear viscosity data evaluated at selected temperatures (345-375°C) were interlinked to the PVT data at pressures ranging from 1 to 200 MPa. According to the recently proposed correlation approach, a pressure-dependent shear viscosity is derived from the relationship (verified on several commodity polymers) between temperature-dependent viscosity and a free volume parameter computed using the Simha-Somcynsky equation of state. Finally, the predicted pressure-viscosity coefficient was compared with the value obtained experimentally on a modified single piston rheometer.
