This work reports the design of polymer micelles with cross-linked ionic cores that display high stability. Block ionomer complexes were utilized as a micellar template for the synthesis of the cross-linked micelles. Such micelles represent hydrophilic nanospheres of core-shell morphology. The core comprises a network of the cross-linked polyanions, which is surrounded by the shell of hydrophilic PEO chains.
