Superstrong segregation limit

The micelle formation is not restricted to solvents for polystyrene but also occurs in very unpolar solvents, where the fluorinated block is expected to dissolve. Comparing the data, we have to consider that the micelle structure is inverted in these cases, i.e., the unpolar polystyrene chain in the core and the very unpolar fluorinated block forming the corona. The micelle size distribution is in the range we regard as typical for block copolymer micelles in the superstrong segregation limit.2,5,6 The size and polydispersity of some of these micelles, measured by DLS, are summarized in Table 10.3. 

Owing to their amphiphilicity and a balanced molecular architecture these molecules from micelles in all solvents for polystyrene as well as in solvents for the fluorinated block. The structure parameters of these micelles have to be regarded as typical for other block copolymers in the superstrong segregation limit.5 6...
