hyperbranched copolymers. The copolymers with less branched
shells had higher values of Tm and DHm.
These amphiphilic hyperbranched copolymers could be used
as nanocarriers to efficiently accommodate the hydrophilic
guests, including MO, CR and DB, into the hydrophilic ami-
dated PEI core. The dendritic structure of the shell of these new
nanocarriers contributed pronouncedly to their superior encap-
sulation performance over the nanocarriers with linear shells. As
far as the weight ratio of the encapsulated guests to the nano-
carriers was concerned, the nanocarriers with branched and
linear shells could be tuned to have a similar encapsulation
capacity for the small MO with a mono-sulfonate group.
However, the nanocarriers with branched shells could be
modulated to have a much superior encapsulation capacity to the
nanocarriers with linear shells, for the larger CR and DB with
multi-sulfonate groups.

From the experimental results, it can be concluded that for the
effective enhancement of the guest encapsulation performance of
amphiphilic dendritic polymers, besides the well-known methods
of increasing the size and polarity of the core, the introduction of
branching units in the shell is also an effective method.
