摘　　要：以KMnO4为引发剂 ,进行了魔芋粉与丙烯酸的接枝共聚反应 .研究了魔芋粉预氧化时间、引发剂浓度、单体浓度、酸度、反应时间和反应温度等聚合条件对接枝效率的影响 .并对其接枝机理作了探讨 .The graft copolymerization of acrylic acid onto konjac glucomannan (KGM)was studied using potassium permamgamate as an initiator. The influences of polymerization conditions such as preoxidation time of KGM, initiator concentration,comonomer concentration,H 2SO 4 concentration,reaction temperature and reaction time on the graft efficiency of the graft copolymerization were investigated. The mechanism of the graft coplymerization was also disscussed.
