Core-shell-corona macromolecular architectures <em>via</em> electrostatic co-assembly

Water-soluble macromolecular complexes are prepared <em>via</em> electrostatic co-assembly of a micelle-forming (non-ionic hydrophobic/ionic) diblock copolymer, polyisobutylene-<em>block</em>-poly(sodium methacrylate), with a double hydrophilic (ionic/non-ionic hydrophilic) diblock copolymer, exhaustively quaternized poly(2-vinylpyridine)-<em>block</em>-poly(ethylene oxide), taken at the equimolar (1 : 1) ratio of their ionic groups. The original micelles appear to act as templates, leading to compartmentalized (core-shell-corona) nanosized macromolecular architectures with a hydrophobic polyisobutylene core, an interpolyelectrolyte complex polymethacylate/poly(2-vinylpyridinium) shell, and a hydrophilic poly(ethylene oxide) corona.
