摘　　要：利用正丁基锂（ｎＢｕＬｉ）与炭黑（ＣＢ）表面含氧基团反应制得了表面含—ＯＬｉ基团的反应型炭黑，以该炭黑与聚氧乙烯聚氧丙烯聚苯乙烯（（ＰＥＯＰＰＯＰＳ）ｎ）多嵌段聚合物组成了阴离子引发中心，使苯乙烯和丙烯腈在炭黑表面产生阴离子接枝聚合反应．ＦＴＩＲ和ＴＥＭ结果证实了其为接枝反应．A reactive carbon black having OLi groups on its surface was prepared by using a reaction between oxygencontaining groups on carbon black surface and nbutyl lithium. The anionic graft copolymerization of styrene and acrylonitrile onto such a carbon black in the presence of polyoxyethylenepolyoxypropylenepolystyrene multiblock copolymer as initiation center has been investigated. FTIR and TEM observations confirmed the graft copolymerization.
