Summary: Amphiphilic hyperbranched polyester (H20‐AM) with methacrylate end groups was synthesized based on hyperbranched aliphatic polyester (Boltorn™ H20). Narrow‐dispersed crosslinkable vesicles were obtained by dissolving H20‐AM in water, and characterized by laser light scattering and TEM. The hollow structural vesicle is composed of around 350 H20‐AM molecules, having a radius of around 40 nm and $\overline M _{\rm w}$ of 1.9 × 10 6 g · mL −1 . The vesicles were fixed by crosslinking of methacrylate groups to form shape‐persistent structures.TEM images of the crosslinked vesicles at lower magnification.
