Abstract
The radial temperature profiles of a polypropylene melt were examined at a point along the barrel of a twin screw extruder, using a novel thermocouple sensor. The flow patterns of the polymer melt were also investigated, the results being used to explain the changes in temperature of the melt during the flow. It was found that the melt temperature profiles and the how patt erns of the polymer melt were closely related. The heat conduction, shear h eating, and the flow length of the material in the barrel of the extruder h ad considerable effects on the melt temperature. (C) 2000 Elsevier Science Ltd.
