摘　　要：利用60Coγ射线对苯乙烯-丁二烯-苯乙烯(Styrene-Butadiene-Styrene,SBS)嵌段共聚物进行辐射接枝改性。研究了SBS/甲基丙烯酸甲酯(Methylmethacrylate,MMA)溶液体系的辐射接枝共聚反应,探讨了辐照剂量、单体浓度、SBS型号对接枝率的影响。并用红外光谱(FT-IR)对接枝共聚物进行了表征,用差示扫描量热仪(DSC)测量了接枝共聚物SBS-g-MMA的热性能。This paper introduces mainly experimental results of graft copolymerization of sty- rene-butadiene-styrene (SBS) with methyl methacrylate (MMA) in solution by γ-ray irradiation. Effects of irradiation dose and monomer concentration on mass increment and graft yield onto two types of SBS have been discussed. FTIR characterization of the irradiated samples showed that the monomer had been grated to the SBS molecular chains, while thermal performance of the graft products, SBS-g-MMA, was measured by DSC.
