摘要： 用UV、FTIk、DSC、TG和DTA及GPC等方法证明了通过三步反应(氯甲基化,叠氮化,环加成反应)确实将C60引入到聚苯乙烯的侧基上,C60基本上以单取代的方式存在,并通过TG和DTA方法估算了C60在聚苯乙烯C60衍生物中的含量。

Abstract: Various methods,such as UV,FTIR,DSC,TG & TAand GPC,were employed to characterize polymeric C60 derivatives.The UV spectra of polymeric C60 derivatives were obviously different from C60 or PS,the similar results were also obtained from FTIR.For all the polymeric C60 derivatives,only a single galss transition temperature was observed in each case,and the values for the glass transition temperatures were found to increase with increasing amount of C60 in the derivatives.All experimental results proved that C60 was covalently linked with the side group of polystyrene through three-step reactions,i.e.,chloromethylation,azidization,cycloaddition.GPCand UVresults also showed that fullerene C60 was mainly monosubstituted.The contents of C60 in the polymeric derivatives were estimated by the TG method.

Key words: Polystyrene C60 derivatives, Monosubstituted polymeric C60 derivatives, C60
