摘　　要：首次以过硫酸铵－硫代硫酸钠（ＡＰＳ－Ｎａ＿２Ｓ＿２Ｏ＿３）为引发体系，研究了丙烯酸丁酯与甘薯淀粉的接枝共聚反应规律，对产物结构进行了表征。Abstract The graft copolymerization of butyl acry-late(BA )and sweet potato starch was carriedout usibng APS-Na_2S_2O_3 as initiation system.The reaction products were characterizated byIR,SEM and X-ray diffract method.The maximum G%and E%were observed at[APS] of 6.0×10￣(-3)mol/L,[BA]at 6～7×10￣(-1)mol/L and a solid liquid ratio of 4:100 at50℃for 4h.
