摘　　要：聚苯乙烯 (PS)在苯溶液中与溴代丁二酰亚胺 (NBS)反应 ,经分离提纯得到了固体溴代聚苯乙烯(PSB)。将所得 PSB溶于苯并与低分子量的聚二甲基硅氧烷硅醇锂 (PDMSOL i)反应 ,经分离提纯得到固体的溴代聚苯乙烯接枝聚二甲基硅氧烷 (PSB- g- PDMSO) ,所得 PSB- g- PDMSO的结构经 1H- NMR、IR及 TEM表征。The bromopolystyrene (PSB) was synthesized by the reaction of polystyrene withN bromosuccinimide (NBS) in benzene at 60 ℃. And then, the graft copolymer, the bromopolystyrene with oligo dimethylsiloxane side chain, was prepared by using a substitution reaction on the bromopolystyrene with monolithium salt of the siloxanediol in N,N dimethylformamide (DMF) at 60 ℃. The graft copolymer (PSB g PDMSO) obtained was characterized by 1H NMR, IR and TEM.
