dc.description.abstractPolypropylene/Polyamide (PP/PA) blends have been prepared and the ef-fect of adding compatibilizer copolymer and nanosilica to the blends has been studied. Microscopic analysis shows that the blends exhibit an emulsion-like morphology, with polypropylene as a continuous phase. The addition of a compatibilizer, as well as nano-silica particles, reduces significantly the size of PA droplets. When the binary blend is submitted to a continuous flow, coalescence of PA droplets may occur, which leads to an increase of the droplets. However, for the blends containing copolymer or nanosil-ica, the flow does not induce changes in the morphology. Oscillatory flows have been carried out to obtain viscoelastic properties of the different blends. In this work, it is proved that the relaxation spectrum obtained from viscoelastic results are able to detect morphological changes.; Polipropileno/Poliamida (PP/PA) nahasteak prestatu dira eta kopolimero-konpatibilizatzailea eta nanosilika gehitzeak nahaste horietan duen eragina aztertu da. Azterketa mikroskopikoak erakusten duenez, nahasteek emultsio antzeko morfologia dute, polipropilenoak fase jarraitua osatzen duelarik. Konpatibilizatzailea zein nanosi-lika gehitzeak PA tanten tamaina nabarmen murrizten duela antzematen da. Nahaste bi-tarrak fluxu jarraitu baten eraginpean daudenean, PA tanten koaleszentzia gerta daiteke eta, ondorioz, tanten tamaina handitu egiten da. Kopolimeroa zein nanosilika daukaten nahasteen kasuan, ordea, morfologia ez da eraldatzen fluxuaren eraginez. Fluxu oszi-lakorrak burutu dira nahaste desberdinen ezaugarri biskoelastikoak lortzeko. Neurketa biskoelastikoen bidez lortzen diren erlaxazio-espektroen azterketak morfologian gerta-tutako aldaketak detektatzeko gai direla frogatzen da.
