Abstract: Anovel C60-styrene-maleic anhydride copolymer was prepared with radical polymerization. 50 mg of C60 and 1 g of styrene and 1 g of maleic anhydride were dissolved in20 mLof o-dichlorobenzene, then was initiated by 200 mg of BPOat 70 ℃ under the protection of Ar for 32 h. The copolymer was obtained as a brown solid. The structure of copolymer was characterized by UVand FTIR. GPCanalyses shows that its average molecular weight Mw is 13000. The copolymer is soluble in THF, DMSOand water. The surface tension of 0.5% of copolymer aqueous solution was determined to be 54.6×10-3N/m(20 ℃). TEManalyses shows that the copolymer is a kind of water-soluble nanosphere with the average diameter of about 60 nm.
