【 摘 要 】

A new pressure cell is described to measure the flow behaviour of polymer melts in dependence of temperature and pressure. Special attention is laid on the construction and functionality of the pressure cell. The pressure cell can be pressurized up to 120 bar and is heatable up to 260ºC. As a measuring geometry a plate-plate-system is used which is capable of characterising high viscous fluids. First results with high viscous silicone oil show good agreement with known references in literature.
