Description	Extrusion of immiscible polymers under special conditions can lead to creation of microfibrillar-phase morphology, ensuring significant increase of mechanical properties of polymer profiles. Polyethylene/polypropylene blend extrudates with microfibrillar-phase morphology (polypropylene microfibrils reinforcing polyethylene matrix phase) were prepared through continuous extrusion with semihyperbolic-converging die enabling elongation and orientation of microfibrils in flow direction. Structure of extruded profiles was examined using electron microscopy and wide-angle X-ray scattering. Tensile tests proved that extrudates with microfibrillar-phase morphology show significantly higher mechanical properties than the conventional extrudates.
