    • ΧN = 18; i.e., the shortest chains are weakly anchored to the interface and are pulled free into the opposing phase. Inspection of Figure 5 of ref 9 demonstrates the swelling of both the monodisperse and polydisperse phases as PDI is increased in the hexagonally packed cylindrical morphology. This spreading of B monomers throughout a microphase-separated AB diblock copolymer melt would produce a decrease in scattered intensity since the electron density contrast between the phases would be reduced.

This spreading of B monomers throughout a microphase-separated AB diblock copolymer melt would produce a decrease in scattered intensity since the electron density contrast between the phases would be reduced. Calculations done in the course of this study using the Sides and Fredrickson methodology have demonstrated this to occur in lamellar systems as well. It should be noted however that as expected, as segregation increases, the infiltration of one domain by even short segments of the other component occurs increasingly less.
