    • One notable exception is BICs formed by double hydrophilic block copolymers containing polyion and nonionic water-soluble chains.1,2 Such BICs self-assemble into micelles with a polyion complex core and nonionic polymer shell, which can be stable in aqueous dispersion even at stoichiometric composition upon complete neutralization of charges

    • Notably, the fluorescence quenching in the {PEVP/PS-b-PMANa + PS-WMA*Na system cannot not be explained by exchange of PS-b-PMA*Na chains between free micelles and BIC particles, since according to ref 34, such exchange is prohibited for PS-WMAA micelles in aqueous media. In other words, changes in fluoresce intensity in these systems are caused only by reaction II.

    • The average concentration of ionic groups [ionic groups]shell was calculated as XionicNw/[4/3N AπRh3 10-24- MPSN wXPS/1000ρ, where Xionic is the polymerization degree of the ionic block, Xps is the polymerization degree of the PS-block, NA is Avogadro's number, MPS, 104 g/mol is the molar mass of the PS unit,ρ= 1.04 g/cm3 is the density of polystyrene in a bulk, and Rh, is expressed in nanometers
    • h, is expressed in nanometers.
