While it was found previously [Macromolecules 1997, 30, 3519] by microcalorimetric titration that in a similar system (PEO176−PMAA186) crystallization of aliphatic tails of N-dodecylpyridinium bromide did not occur, in our system it was evidenced by SAXS that upon addition of DPCl to fully ionized PEO705−PMAA476 the ordered arrangement of the surfactant occurs in a certain range of PEO705−PMAA476 concentrations and surfactant-to-polyelectrolyte charge molar ratio.
