摘　　要：通过三羟甲基丙烷和2-溴异丁酰氯反应合成了三臂星型聚合物引发剂,利用原子转移自由基聚合合成了三臂星型的聚甲基丙烯酸甲酯,并对引发剂和聚合物的结构进行了1H NMR和GPC的表征,合成了聚合物分子量分布较窄的端基含溴原子的三臂星状聚合物.A trifunetional initiator is successfully synthesized by the reaction of trimethylol propane with 2- bromoisoburyryl chloride. Then Three-arm Star-shaped polymers are synthesized by atom transfer radical polymerization. The initiator and the star polymers are characterized by ^1H NMR and gel permeation chromatography （GPC）. Three-arm Star-shaped polymers with end group bromine atom are obtained and the polydispersity of the polymer is relatively narrow.
