    • Eisenberg has pointed out that "monodisperse" polymers, even with a polydispersity ratio of 1.03, which is considered very good in anionic polymerization, have a significant distribution width around the most probable degree of polymerization and that this can have a profound influence on the micellization behavior (Gao, Z.; Eisenberg, A. Macromolecules 1993, 26, 7353).

    • Moffitt, M.; Eisenberg, A. Chem. Mater. 1995, 7, 1178, 1185. Note that "ionomers" often refer to diblock polymers with one charged segment. In a typical study the solvent is hydrophobic so that ion pairing forces the charged segments to form a "core" structure, either in solution or in films. In many cases the term ionomer can be taken to be synonymous with an amphiphilic diblock polymer. However the term ionomer can also be applied to random copolymers with a small fraction of charged groups (e.g. see: Eisenberg. A.; Hird, B.; Moore, R. B. Macromolecules 1990, 23, 4098. Eisenberg. A., Ed. Ions in Polymers; Advances in Chemistry Series 187; American Chemical Society: Washington, DC. 1980).

    • 3/5a, where g is the number of monomer units in the blob and a is the size of a single monomer. For the electrostatic blob the size is determined by the linear charge density and the dielectric constant of the medium, and more importantly, the blob size is not a function of the radial position of the segment.

    • The exchange of fluorescently tagged polymers has been measured by several groups. See. for example, (a) Rager, T.; Meyer, W. H.; Wegner, G.; Winnik, M. A. Macromolecules 1997, 30, 4911.

For a glassy polymer core the rate of polymer exchange is expected to be immeasurably slow unless the block length is very short.
