AbstractTo take advantage of the superior oxygen gas barrier property of ethylene-vinyl alcohol random copolymer (EVOH) and the balanced mechanical properties of polyamide (PA), blend morphologies with high interfacial areas at constant compositions were produced with a laboratory chaotic advection blender. This new processing technology intrinsically develops blends having very high interracial area so it has special applicability to barrier films. Even with influences from component interactions, multi-layer films with submicron layer thicknesses were formed. The layers became finer for more extensive chaotic advection, as has been documented earlier in immiscible, nonreacting polymer blends. Influences of structure on impact toughnesses are specifically reported.
