Different from LDBCs, linear-hyperbranched block copolymers
(LHBCs) are usually synthesized by an one-step reaction
[7–9]. Recently, many synthetic strategies for the LHBCs
were reported, among them the ring-opening multibranching
polymerization (ROMBP) of glycidol was employed for the
generation of the hyperbranched polyglycerol (hbPG) block
onto a linear macromolecular Bcore^ via Bgrafting-from^
strategy. Furthermore, the DP,Mw/Mn and DB of hyperbranched
moieties were efficiently controlled by slow monomer addition
(SMA) method, almost perfect hyperbranched structures were
obtained [10–14].
