Ultrasound and dielectric measurements are used to measure the instantaneous density and viscosity of polymer melts during PVC extrusion process. The acoustic properties of the polymer melt, measured by a 2.25 MHz ultrasound transducer mounted on a special die adapter, are correlated to the melt den
