Abstract The effect of addition of an ethylene‐propylene block polymer on rheological and mechanical properties of a linear‐low‐density polyethylene/polypropylene blend was examined. The samples were prepared by melt blending in a twin‐screw extruder followed by injection molding. The single‐, two‐ and three‐component systems were treated the same way. The mechanical behavior of the blends was evaluated by means of tensile, and flexural, tests at 23 and −40°C. The capillary, elongational, and dynamic‐flow measurements were performed at 190°C.
