In this study, polypropylene grafted with maleic anhydride (MAH) [(PP-g-MAH)] and poly[methylene (phenylene isocyanate)] (PMPI) were employed as dual compatibilizers in blends consisting of a polyester hot melt resin and a poly-a-olefin hot melt resin. We report on the specific compatibility and correlation with resultant morphological, thermal and mechanical properties. In particular, we demonstrate that PMPI can be used as an efficient coupler to improve the compatibility of immiscible polyester.polyolefin blends.
