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 0 14 ,糊化的玉米淀粉与丙焕酸质量比1∶6的比例发生接枝聚合反应。反应温度5 0℃,反应时间2 5h～3 0h ,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率最高,可达到5 6 0g g。
Potassium persulfate as an initiator,super water absorbent resin is synthesized by graft copolymerization of pasting corn starch with acrylic acid(with the ratio of 1/6) at (50 ℃) when the ratio of potassium persulfate to corn starch is 0.014,the neutralization degree of acrylic acid is 92%,the reaction time is 2.5 h—3.0 h.The water-absorbing ability of the water absorbent resin is determined and the water-absorbing rate of the prepared resin can reach 560 g/g at room temperature in neutron medium.
