摘  要:
以硝酸锫铵为引发剂,研究了丙烯腈单体接枝到魔芋葡甘聚糖基体的反应条件,探讨了引发剂浓度、单体浓度、反应温度、反应时间等聚合条件对接枝反应的影响。结果表明:以魔芋葡甘聚糖为原料,丙烯腈为单体,通过硝酸锫铵引发制得接枝魔芋葡甘聚糖的最佳工艺为:引发剂浓度0.01mol/L,单体浓度1.6mol/L,反应温度50℃,反应时间3h。红外光谱和X衍射表明魔芋葡甘聚糖与丙烯腈发生了接枝共聚反应。

摘  要:
Optimization of concentration of initiator, reactant, temperature and time respectively on effects of grafting of acrylonitrile and konjac glucomannan (KGM) initiated by ceric ammonium nitrate were studied. The results showed that optimization conditions of grafting are: concentration of initiator 0.01 mol/L, reactant concentration 1.6 mol/L, temperature 50 ℃ and time 3 h. The graft copolymerization is confirmed by IR and X-ray diffraction.
