## Abstract This study was concerned with the structural features and mechanical properties of polypropylene (PP)/lowβdensity polyethylene (LDPE) blends, which after compounding were modified by the freeβradical grafting of itaconic acid (IA) to produce [PP/LDPE]β__g__βIA in the course of reactive
Grafting reactions were performed in a Haake torque rheometer, according to a central composite experimental design, where the maleic anhydride and peroxide concentrations, rotor speed, and reaction time were varied. The 27 formulations were analyzed by Fourier transformed infrared spectroscopy and
