Description	The electrostatic coassembly of a block copolymer polyelectrolyte poly(ethylene oxide-block-poly-(methacrylic acid), PEO705PMAA476, and oppositely charged surfactant, N-dodecylpyridinium chloride (DPCl), has been investigated by a combination of isothermal titration calorimetry (ITC), spin-echo NMR spectroscopy, and time-resolved SAXS measurements. The results reveal new insight into the thermodynamic and kinetic behavior of the self-assembling system. The most important finding obtained by stopped-flow time-resolved SAXS measurements concerns the surprisingly high rate of processes of creation of structurally ordered cores of self-assembled surfactantpolyelectrolyte nanoparticles (<50 ms).
