For the dBCP micelles with lower P4VP fractions (lower degree of polymerization of the P4VP block) the partial swelling of the core in THF is more pronounced leading to larger core diameters compared to the dried state. In Figure the three diameters Dh, Dcore and Dcryo are plotted vs. the P4VP fraction revealing the almost linear correlation for all three parameters. a) Subscripts denote the content of the respective block in wt%, superscript gives the number average molecular weight in kg mol -1 ; b) calculated from 1 H-NMR measurements utilizing the absolute molecular weight of the PS precursor derived from MALDI-ToF MS; c) determined by DMF-GPC calibrated with narrowly distributed PS standards (Figure ); d) calculated from 1 H-NMR measurements (for an exemplary calculation see Figure ).
