The intrinsic viscosity (IV) measured by online capillary rheometers is determined via a correlation relationship between shear viscosity or melt flow rate (MVR) and intrinsic viscosity.
Polymer processing or polymer compounding is often controlled by so called ONLINE-RHEOMETER that are essential for real-time process control...
Online process monitoring of rheological properties in polymerization and pilot plants is essential for fast and effective process control of polymer production.
