| 摘 要： | 采用自由基聚合法 ,以过硫酸铵为引发剂 ,淀粉与丙烯酸钠和丙烯酸钾进行接枝共聚 ,首次合成了含钾的高吸水树脂 ,详细考察了 KOH对丙烯酸的中和百分比对吸水保水剂的吸液性能的影响。合成的吸水保水剂在钾的绝对含量约 1 .5 %时 ,吸纯水可达 70 0～ 72 0 g/g,吸自来水可达 2 40～ 2 5 0 g/g,吸 0 .9% Na Cl溶液可达 5 9～ 62 g/g。

| Abstract: | High water-absorbing and water-keeping super absorbent was synthesized by graft copolymerizing starch with sodium acrylate and potassium acrylate in presence of ammonium persulfate as initiator. Through experiments we discuss the influences on the water absorbability by the neutralization ratio of KOH to crylic acid. |
