摘　　要：自制酸变性淀粉和水包水乳液,并用其合成淀粉接枝聚丙烯酰胺。对影响产物接枝效率,溶解时间的因素,如温度、丙烯酰胺量、引发剂量、硫酸质量浓度等进行了讨论,得出了合成酸变性淀粉接枝聚丙烯酰胺乳液的最佳合成方式及各种试剂的最佳投入量。Acid modified starch and water-in-water emulsion were made in laboratory, and St-AM was synthesized in water-in-water. Factors that effect graft efficiency, dissolving time of production were discussed such as temperature, acrylamide quality, initiator quality, vitriol quality concentration and so on. Conclude the best way of synthesizing acid modified St-AM emulsion and the best dosage of diversified reagents.
