    • We have assigned the morphology of SI(0.64,1.12)-9 as perforated lamellae (P, however, coexisting lamellae (L) and poorly ordered hexagonally packed cylinders (C) is also a possibility consistent with our scattering results. The PL morphology was predicted by Matsen to remain metastable in polydisperse block copolymer melts as it is in the monodisperse case.29
