摘　　要：用焦磷酸络锰的三价离子 Mn3 + 为引发剂 ,引发魔芋粉 (KGM)与丙烯酰胺 (AM)的接枝共聚。研究了引发剂浓度、单体浓度、p H值、反应温度、反应时间、反应介质以及 KGM预处理方式等对接枝反应的影响 ,同时 ,还研究了产物的水溶性及增稠性。The graft copolymerization of acrylamide onto konjac glucomannan(KGM) was studied using manganese pyrophosphate complex as an initiator. The effects of initiator concentration and comonomer concentration and pH value and reaction temperature and time and medium, as well as the pretreatment temperature of KGM on the graft copolymerization were investigated. The water solubility and thickening properties of the graft copolymers were also studied.
