[13] investigated the pressure coefficient of melt viscosity using a high-pressure sliding plate rheometer (HPSPR) and capillary rheometers with driven piston and nitrogen counter-pressure to control the capillary exit pressure; they found that the pressure coefficient of viscosity, [??], agreed fairly well with data from different laboratories and instruments.
