A series of palmitoyl chloride-grafted hyperbranched polyglycerols were
synthesized through cationic ring-opening polymerization and end-group
modification. The obtained grafted copolymer of HPG-C16 possesses a
hydrophilic hyperbranched polyether core and many hydrophobic alkyl
arms, which shows interesting self-assembly behavior in THF and water.
The results indicate that the copolymers with a relatively high alkyl
grafting ratio can form unimolecular micelles in THF and will further
assemble into giant vesicles around 1–10 μm in THF/water mixed solvents.
However, the HPG-C16 with a low alkyl grafting ratio of 15.6% can
directly assemble into vesicles in THF and form micelles in water.
