摘要：

A polyfunctional 1,1-diphenylethylene (DPE) agent was prepared by ring-opening metathesis polymerization of a DPE-functionalized norbornene monomer. Its reaction with sec-butyllithium gave a novel polyfunctional anionic macroinitiator with one 1,1-diarylalkyllithium initiation functionality per repeating unit. The significant applicability of this polyfunctional anionic macroinitiator was demonstrated by its excellent initiation efficiencies in anionic polymerization and a preparation of a graft copolymer with well-controlled long and dense diblock grafts.
