Özet

In this study, we prepared polypropylene (PP) blends with commercially available amphiphilic diblock copolymer poly(ethylene-block-ethylene oxide) (P(E-b-EO)). Selective surface enrichment of the diblock copolymer used was observed only on the PP blend extrudates which were prepared using capillary rheometer with different wall shear rates showing that flow processes play an enormous role in surface migration.
