The amorphous phase and crystalline morphology of the poly(vinyl methyl ether) (PVME)/poly(1,6-hexamethylene adipate) (PHA) blend were compared with those of the classical PVME/poly(ɛ-caprolactone) (PCL) system, isomeric to the former. Both blend systems’ amorphous phases are similarly miscible with χ12=−0.2. In contrast, the crystalline phases of these two blends differ significantly. When crystallized at high Tc (46 °C or above), the PVME/PCL (20/80) blend assumes fluffy feather-like dendrites (Graph-a), which are dramatically different from straight-stalk dendrites in the PVME/PHA (20/80) blend (Graph-b).
