Morphology and Elastic Properties of PP/EVA Polymer Blends

Abstract: Several polypropylene–ethylene vinyl acetate (PP/EVA) copolymers with compositions ranging from 90/10 to 10/90 PP/EVA were prepared and characterized in terms of their morphology by transmission and scanning electron microscopy, and their mechanical properties were also studied. The results show a wide range of spatial structures which correlate well to the corresponding measurements of elastic modulus of the blends.

“…Earlier studies on PP/EVA blends have proved EVA as an impact modifier for i‐PP 10, 11. While linear viscoelastic and transient behaviors were studied by Tyagi and Ghosh,12 the morphological, mechanical, and rheological properties of these blends using homopolymer polypropylene were reported by several researchers in separate studies 13–16…”

“…5 In this case, compatibilizer such as modified PP (PPgMA) can increase the miscibility of components. 6,7 Although the impact strength increases by inclusion of rubber particle, the stiffness of PP decreases.…”

“…Since the RuO 4 ‐stained TEM micrographs cannot afford enough contrast between PP and EVA phases for compatibilized PP/PA6 blends, the selective‐etched experiments were chosen to further allow a clear identification of phase morphologies of EVA‐ g ‐MA components. The specimens were freeze‐fractured in liquid nitrogen and were then etched with toluene for 24 h at ambient temperature to dissolve EVA phase 24–27…”
