Abstract

The dielectric slit die is a new instrument designed for real-time monitoring of polymer compounding. It is a multi-purpose sensing device for measuring dielectric, rheological and optical properties during extrusion. The instrument is mounted at the exit of an extruder and consists of a slit with dimensions 2 mm high, 28 mm wide by 15 cm lenght along which are situated dielctric, pressure and optical sensors. A flexible design permits interchanging of sensor locations and the addition of new sensors as needed. We demonstrate the operation of the slit die with real-time monitoring of polymer/clay nanocomposites compounding.
