The non‐membrane‐closing formation of polymer vesicles was demonstrated by the self‐assembly of an amphiphilic hydrogen‐bonded interpolymer complex of HPC and PAA. A dynamic‐formation process that involved a nucleation and growth pathway was observed experimentally that was different from the theoretical predictions of both the membrane‐closing model and the nucleation and growth model. A series of intermediate states between the solid spheres and vesicles were visually captured by the addition of an inorganic salt followed by dilution.
