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
