| Abstract: | The phase morphology of polypropylene/poly (ethylene-co-octene) /polyamide 6 (PP/POE/PA6) ternary blend was predicted by using spreading coefficient and minimum free interfacial energy models. The results showed that a core (PA6) -shell (POE) structure was formed. The PP/POE/PA6 (50/25/25,mass ratio) ternary blends were prepared through two mixing sequences and their phase morphologies were investigated. It was demonstrated that when three components were blended together, POE and PA6 droplets were distributed independently in the PP matrix. When POE was blended with PA6 first, and PP was then added, both PA6 droplet and fibril were formed. For POE, some migrated into PP phase and some other encapsulated small PA6 droplets or adhered to the surface of the large PA6 fibrils. Thus, POE phase was located between PA6 and PP phases and played the role of connecting the two phases. |
