A
novel pH-responsive polymer vesicle obtained by the aqueous
self-assembly of carboxy-terminated hyperbranched polyesters is
reported. The synthesis is very simple, just a one-step esterification
of the commercially available hydroxy-terminated hyperbranched polyester
of Boltorn Hx (x?=?20, 30, 40) with succinic
anhydride. The vesicle size can be controlled from 200 nm to 10 μm by
simply adjusting the solution pH as well as the degrees of branching (or
generation).
