Summary

Binary blends of linear PE sharp fractions [Mw=2 500 (L2.5) and 66 000 (L66)], all crystallized at the temperature of the transition between regime I and regime II growth, have been studied by TEM after Kanig treatment. It is shown that the dominant lamellae are always long and straight and form stacks. The number of lamellae in these stacks decreases with increasing content of L2.5. The lamellar width perpendicular to [010] is 1–3 μm for L66 and the 50/50 blend, but anomalously high for the 80/20 (L2.5/L66) blend. Thin subsidiary lamellae are observed only in the 50/50 and 80/20 blends. A significant fraction of these samples contains domains of segregated L2.5 showing no lamellar contrast.
