ResumoLiving polystyrene with TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) end groups and C60 in molar ratios of 1:1 to 4:1 were heated in 1,2-dichlorobenzene solutions to 80−130 °C to produce polymers containing C60 units. Multidetector size exclusion chromatographic (SEC) analyses of the recovered polymers showed molar masses corresponding with one, two, and sometimes three of the polystyrene chains. The one-chain components were mixtures of fullerene-containing and fullerene-free macromolecules. The two-chain components contained an average of one fullerene unit per macromolecule, and the three-chain components contained an average of more than one fullerene per macromolecule. Analogy to low molar mass diadducts of alkyl radicals to C60 indicates that the polymeric diadducts are isomeric mixtures.
