摘 要:在 n-BuLi引发的丁二烯负离子聚合中,首次用 C60Cln/C70Cln作为偶联剂进行偶联反应,并对偶联产物进行了粘度测试和 GPC表征.GPC图中出现的新峰证明偶联产物的存在.粘度曲线则随偶联剂用量的增加出现双峰变化,这和用 SiCl4偶联时出现的单峰不同 .

  The unique structure and properties of fullerene(C60/C70) have attracted extensive attentions in the field of macromolecule.By now,all kinds of polymers containing C60/C70 have been prepared. Furthermore,the important branch of fullerene family- fullerene halide,with unique architectures and novel property,has also been studied[1~ 2].
  This paper introduced fullerene halide- C60/C70 chloride(C60Cln/C70Cln). Its coupling behavior in anionic polymerization of butadiene(Bd) with n-BuLi as initiator was investigated in our laboratory for the first time.The results showed that C60Cln/C70Cln has the specific coupling behavior.
