摘要：

A convenient three-step strategy has been developed for the preparation of well-defined amphiphilic, linear-hyperbranched block copolymers by hypergrafting. The synthetic procedure is based on a combination of carbanionic polymerization with the alkoxide-based, controlled ring-opening multibranching polymerization of glycidol. A linear AB diblock copolymer polystyrene-block-polybutadiene (PS-b-PB) with narrow polydispersity was obtained by amionic copolymerization. Subsequent hydroxylation by hydroboration led to PS508-b-(PB-OH)(56), used as macro-initiator for the polymerization of glycidol under slow monomer addition conditions.
