摘要
以过硫酸钾为引发剂,过硫酸钾与玉米淀粉的质量比为0.014;糊化的玉米淀粉与丙烯酸按质量比1∶6的比例发生接枝聚合反应。反应温度50℃,反应时间2.5 h^3.0 h,丙烯酸的中和度为92%,制得高吸水性树脂,并讨论了其吸水性能。在室温、中性酸度环境下,合成的高吸水性树脂吸水倍率最高,可达到560 g/g。
Under the action of potassium persulfate as the initiator, the ratio of potassium persulfate and corn starch was 0. 014. The graft polymerization occurred between the pasting corn starch and acrylic acid with the ratio of one over six from which the super water absorbent resin was prepared. The reaction temperature was fifty centigrade and the reaction time was 2. 5 h～3.0 h, the neutralization degree of the acrylic acid was 92%. The water-absorbing properties of the super water absorbent resin were discussed through experiments. The prepared super water absorbent resin has the highest water-absorbing rate which is up to 560 g/g.
