摘要：

Anionic polymerization of methyl methacrylate(MMA),n-butyl methacrylate(nBMA)and glycidyl methacrylate (GMA)initiated by nBuCu(NCy2)Li(1)in tetrahydrofuran(THF)at-50℃to-10℃was investigated.It was found that the polymerization of MMA and nBMA initiated by 1 proceeded quantitatively in THF to afford PMMA and PBMA with polydispersity index 1.15-1.30 and nearly 100%initiator efficiencies at-10℃.The molecular weights increased linearly with the ratio of[monomer]/[1].However,a post-polymerization experiment carried out on this system revealed a double polymer peak by GPC when fresh monomer was added after an interval of 10 min.Polymerization of styrene could be initiated by 1,but the initiator efficiency was low.
