C60-end-bonded polystryrenes(PS-C60-Br) with narrow molecular weight polydispersity were prepared by atom transfer radical polymerization (ATRP) in good yield.GPC results show that the polydispersities of these fullerene polymeric derivatives were between 1.1 and 1.3.The brown color of the solution indicates that C60 has been bonded into the polymer

which was confirm by UV-vis.Furthermore

2-amino-acetonictrile was used as an IR label to react with PS-C60-Br

and the product show the characteristic absorption of CN GROUP AT 2369cm-1.These results reinforce the conclusion that C60 has been covalently bonded into the polymer.A polssible mechanism of the formation of C60-end-bonded PSt was deduced tentatively.
