摘要: 通过由萘钠引发得到的聚苯乙烯"活性"双阴离子与C70的反应,合成了哑铃状C70-聚苯乙烯高分子衍生物.产物经UV-Vis,FTIR,GPC,1HNMR,13CNMR,SEM,XRD,TGA和DSC等方法进行表征.GPC测得C70-PS衍生物与其母体PS具有相近的分子量.TGA分析表明,得到C70的含量接近PS链两端各键合一个C70分子,形成线型的哑铃状结构.

Abstract: The dumbbell-like C70polystyrene derivatives were prepared through direct reaction of the "living" dianionic polystyrene obtained by sodium naphthalene-initiated anionic polymerization with C70in the C6H6/THF mixed solvents. The products were characterized by UV-Vis, FTIR, GPC, 1H NMR, 13CNMR, SEM, XRD, TGA and DSC techniques. The GPC analysis showed the C70-styrene copolymers and the parent polystyrene have nearly the same molecular weights. From the GPC data and the C70contents of the copolymers determined by TGA, it was confirmed that the C70-polystyrene derivatives are linear dumbbell-like macromolecules in which two C70molecules end-capped together by a polystyrene chain.

Key words: C70, Polystyrene, Anionic copolymerization, Structural characterization
