Abstract

A series of poly(n-butyl methacrylate)-block-poly(2-(acetoacetoxy)ethyl methacrylate)s (PBMA-b-PAEMA) were studied according to the formation of core−shell micelles in dilute cyclohexane solution (PBMA → shell, PAEMA → core). Although being a strongly segregating system, the appearance of different shapes of micelles could not appropriately be described by simple space-filling arguments within the geometric model of Antonietti and Forster et al. [J. Chem. Phys. 1996, 104, 9956−9970]. The model was refined through introduction of the aspect ratio of the core-forming monomer unit for the calculation of geometric packing parameters.
