The effect of a filler on the compatibility of an immiscible Nylon 6/polypropylene blend is studied. A compatibilized system with maleic anhydride grafted polypropylene is used as a reference. Dynamic mechanical analysis, differential scanning calorimetry and scanning electron microscopy measurements are performed for these two distinct systems containing treated and non‐treated glass spheres. An improvement of the properties towards surface‐induced compatibilization is observed when the filler surface is treated with a suitable silane coupling agent. Changes in the viscosity and main relaxations of the studied system are correlated with the presence of the filler and with its surface treatment. The crystallinity, adhesion and morphology behavior supports the rheological results. In this system, the filler takes not only the usual role of reinforcing material but also a new role as modifier of the interphase structure.
