Melt rheology of high density polyethylene/polyamide‐6 blends

Commercial high density polyethylene and polyamide-6 (PA) resins were melt blended in the Brabender Plasticorder twin-screw extruder. The blends containing zero to 30 wt percent of polyamide-6 were examined in dynamic and steady state shear at 150, 200, and 250°C. The Theological test results are discussed in terms of morphology of the samples as observed under scanning electron microscope. Microscopy of the extrudates has shown a temperature dependent movement of the polyamide in the capillary during the extrusion and that fibrillation of the PA phase in the extensional field occurred at all temperatures.
