摘　　要：C\-\{60\}\|end\|bonded polystryrenes(PS\|C\-\{60\}\|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 C\-\{60\} 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\|C\-\{60\}\|Br,and the product show the characteristic absorption of CN group at 2369cm\+\{-1\}.These results reinforce the conclusion that C\-\{60\} has been covalently bonded into the polymer.A possible mechanism of the formation of C\-\{60\}\|end\|bonded PSt was deduced tentatively.C\-\{60\}\|end\|bonded polystryrenes(PS\|C\-\{60\}\|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 C\-\{60\} 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\|C\-\{60\}\|Br,and the product show the characteristic absorption of CN group at 2369cm\+\{-1\}.These results reinforce the conclusion that C\-\{60\} has been covalently bonded into the polymer.A possible mechanism of the formation of C\-\{60\}\|end\|bonded PSt was deduced tentatively.
