The procedure employed to prepare blends plays a significant role on the ultimate morphological and mechanical properties of the blend. This was demonstrated through the use of a styrene‐ethylene/butylene‐styrene (SEBS) triblock copolymer as a compatibilizer for isotactic polypropylene and linear lowdensity polyethylene. The considerable increases in impact strength for the blends containing the higher percentages of SEBS are related to the magnitude of plastic deformation observed in the matrix and to the size of the occlusions.
