通过吸水倍率的测定研究了各反应因素对反相乳液体系中芋头淀粉-丙烯酸-丙烯酰胺的接枝聚合反应的影响。结果表明:反应温度60℃,单体中和度70%,油水比1.3∶1,交联剂用量0.06 g,引发剂用量1.0 g,反应时间2.5 h时,产物树脂吸水倍率达到了129 g/g,具有较快的吸水速率和较强的再生能力。 The effects of reaction factors on the graft polymerization of taro starch - acrylic acid - acrylamide in the inverse emulsion system were studied by the determination of water absorption capacity. The results showed that when the reaction temperature was 60 ℃, the degree of monomer neutralization was 70%, the ratio of oil to water was 1.3:1, the amount of crosslinker was 0.06 g, the initiator dosage was 1.0 g and the reaction time was 2.5 h, the resin absorbent capacity reached 129 g / g, has a faster water absorption rate and strong regeneration capacity.
