【Abstract】 The poly（methyl methacrylate）with single-caped halogen（PMMA-Br）was synthesized by using atom transfer radical polymerization（ATRP）method under ultrasonic irradiation,with ethylα-bromopropionate as the initiator and CuBr/2,2-bipyridine（BPy）as the catalyst and ligand.Then PMMA-Br as the macroinitia- tor and CuBr/BPy as the catalyst and ligand,the block copolymer poly（methyl methacrylate）-b-polystyrene was synthesized by ultrasonic.Then nanocopper/poly-（methyl methacrylate-b-styrene）composites was suc- cessfully prepared with NaBH₄ as reductant in the polymerization system.The nanocomposites structure were characterizated by means of FTIR,¹H NMR,and GPC result showed that the molecular weight of the block copolymer was about 25 thousand and the polydispersity index（PDI）1.38,XPS proved that there were chemi- cal interactions between nanocopper and the carbonyl of block copolymer.Self-assembling behaviors of block copolymer induced by the nanocopper were investigated by HTEM.更多还原
