Abstract
In order to develop PP (polypropylene)‐based blends with balanced toughness and rigidity, the poly‐blends of PP/PC (polycarbonate)/POE (ethylene–octene copolymer) were prepared by applying styrene–ethylene–propylene–styrene (SEPS) as the macromolecular compatibilizer. The compatibilizing effect was studied in terms of the mechanical, morphologies and thermal properties, and the compatibilized PP‐based blends presented remarkable improvement in impact toughness and balanced tensile strength due to the formed special morphology structure. Additionally, by preparing the pre‐blend of PC/SEPS, the melt viscosity of the PP matrix can match that of the dispersed phase PC and POE, which led to a further improvement in the mechanical property of the blends.
