“…The olefinic polymers applied to blend with PP to modify its impact strength are copolymers based on ethylene, like ethylene-vinyl acetate (EVA), which is also a low-cost polyolefin [22,25,26]. The contribution of EVA to improve the impact strength of PP has been proved [20,[25][26][27] such as the immiscibility between both polymers, due to their completely different chemical structures [25,26,28]. To overcome this problem, the addition of a compatibilizer agent may improve the interfacial adhesion between the PP and EVA phases, modifying its morphology, hence increasing the mechanical properties of the PP/EVA blend [26,29].…”
