The crystallizable component poly(ethylene oxide) (PEO) displays liquid–liquid phase separation in blends with the rigid amorphous aromatic polyamide, Aramide 34I. The crystallization, melting behavior and the semi-crystalline morphology after crystallization from the miscible state, are investigated. It is found that the amorphous component, Aramide 34I, has a pronounced effect on the crystallization behavior of PEO; PEO can only be crystallized up to 35 wt.% of Aramide 34I. A complex melting behavior of PEO with secondary crystallization and recrystallization, in which the amorphous component segregates interlamellarly during crystallization, is described. A lamellar insertion model is proposed for the location of the secondary lamellae.
