Abstract
Ternary blends of Poly(ethylene terephthalate) (PET), Polyamide-6 (PA6) and phenoxy were prepared to compatibilize immiscible blends of PET and PA6. Phenoxy phase during melt mixing was characterized using electron microscopes, SEM and TEM. For PA6 matrix blends, it resided at the interface between PET and PA6 and forms an encapsulating layer during melt mixing. For PET matrix blends agglomerate particles were observed as a result of coalescence even though phenoxy encapsulated minor PA6 phase. The encapsulation of phenoxy onto PET or PA6 was interpreted in terms of a spreading concept combined with solubility parameter. Although phenoxy added as a compatibilizer does not stabilize the morphology it increases the tensile properties of PA6/PET blends.
