摘要： A system and method for measuring viscosity, melt flow index (MFI), and melt volume rate (MVR) of a polymer melt in real-time during an extrusion process to provide quick and accurate feedback for process control. The system includes a polymer processing rate sensor (36), a polymer melt temperature sensor (30), an extruder pressure sensor (32), and a die head temperature sensor (34) for taking in-line measurements during the extrusion process. The in-line measurements are made on the main process stream of the polymer melt, with the determination of viscosity, MFI, and MVR based on these measured values and those obtained during a calibration run with polymers having known properties. The invention can be used in any polymer compounding and extrusion process utilizing die opening with any constant geometry for monitoring quality and providing feedback for process control.

摘要： The present invention relates to a thermoplastic composition that provides improved thermal aging stability along with durability. The thermoplastic composition comprises a polyamide resin, and a polyhydric alcohol, wherein a majority of the polyhydric alcohol particles have a particle size that is less than about 70 microns. It has been found that a combination of a polyamide resin and a polyhydric alcohol with this particle size produces a superior product demonstrating greater thermal stability and durability than the polyamide resin alone.
