Abstract: Aseries of styrene/acrylamide copolymers were synthesized. The PAm molar fraction in copolymers varies from 18% to 33%. Then the C₆₀-containing copolymers were obtained by the reaction of St/Am copolymer with C₆₀in toluene at 30 ℃ and 80 ℃, respectively. The products are orange or brown powders and soluble in common solvents, such as CH₂Cl₂, CHCl₃, toluene, THF etc .. The C₆₀moiety in copolymers varies from 0.49% to 1.45%(weight percentage ratio). The results also show that with the increase of mole percentage of amide group in copolymers, the weight percentage of C₆₀increases while the C₆₀/amide mole ratios in copolymers decline. In addition, raising the reaction temperature enhances the reactivity. The UV-V is spectra show that C₆₀containing copolymers have a stronger adsorption from 400 nm to 500 nm than pure C₆₀and C₆₀doped copolymers have. Increasing the C₆₀content in those samples, the characteristic peak of C₆₀at 330 nm was suppressed gradually by a strong wide adsorption band from 290 nm to 350 nm, which reveals that amide group can react with C₆₀and the C₆₀is chemically bonded to the copolymers.
