摘　　要：研究了苯乙烯(St)、甲基丙烯酸甲酯(MMA)与淀粉的接枝共聚合反应。以焦磷酸锰[Mn(H_2P_2O_7)_3]^(3-)为引发剂,十二烷基苯磺酸钠为乳化剂,考察了引发剂浓度、反应温度、单体浓度对原位聚合反应中单体的转化率(C)、接枝率(G)、接枝效率(GE)的影响。The graft copolymerization of St/MMA onto starch was investigated using manganese py-rophosphate as initiator and sodium dodecyl benzene sulfonate as emulsifier. The effects of concentration of initiators, reaction temperature and concentration of monomers on graft copolymarization have been examined. The monomer conversion ratio( C ), graft degree ( G ) and graft efficiency( GE ) were determined.
