Abstract: Anovel method is adopted to synthesize a new type of polymeric C₆₀ derivatives,in which C₆₀ sites in the main chain of polystyrene.The product was characterized by several methods,The UVspectra show that the living anionic polystyrene species can react with C₆₀.The GPCresults proved that the mount of C₆₀ do not influence the degree of the substi tution, All C₆₀ is bissubstituted.The DSCresults illustrate that only one glass transition temperature was observed in each case.As the weight percent of C₆₀ increased in the polymer,the T_g increased from 94.4℃ (PS) to 96.9℃ (PSC1) and 97.6℃ (PSC2).The obtained polymeric C₆₀ derivative is brown and brittle glass,and the intensity of brown color depends on the amount of C₆₀ in combination, Polymeric C₆₀ derivatives can be dissolved in a variety of solvents,such as THF, toluene, trichloromethane,and so on.Its solubility behavior is similar to polystyrene itself and totally unlike C₆₀.
