摘要
以 KMn O4 为引发剂进行魔芋粉与丙烯腈的接枝共聚反应。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、反应温度和反应物加料方式等聚合条件对接枝效率的影响 。
The graft copolymerization of acrylonitrile(AN) onto konjac glucomannan(KGM) was studied using KMnO 4 as an initiator. The influences of polymerization conditions such as preoxidation time of KGM, initiator concentration, monomer concentration, H 2SO 4 concentration, reaction temperature, reaction time and adding sequence of reactants on the graft efficiency of the graft copolymerization and the conversion of AN were investigated. The mechanism of the graft coplymerization was also disscussed.
