Polymer tethered C60 fullerenes (PTFs) were synthesized by reacting amine terminated polystyrenes with fullerene under ambient conditions. While toluene was employed as the primary solvent in the synthesis, polar co-solvents were incorporated in various ratios to determine their effect on the reaction yield and nature of the product. The resultant PTFs were analyzed by GPC and UV–Vis spectroscopy to determine the number of adducts. The addition of a polar co-solvent was found to significantly affect the reaction rate, yield, and total number of substitutions on the fullerene. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
