architectures exhibit significantly altered physical properties [14][15]. This is often considered the primary motivation for the choice of this interesting polymer architecture [16].
A suitable multifunctional core molecule is required to prepare multi-arm star polymers with core–shell characteristics. Apart
environment when core–shell topologies for encapsulation are desired.
Here we present a solvent-free synthetic strategy for multi-arm star block copolymers with a hyperbranched polyether core and PGA arms, systematically varying arm length. The combination of glycolide with a multifunctional initiator studied
