摘　　要：以过硫酸铵引发玉米淀粉与丙烯酸及其钠、钾盐进行自由基接枝共聚,制得含钾、氮的高吸水树脂。研究了原料配比,氢氧化钾、氨水用量对吸水率的影响。所得吸水剂具有优越的保水性能,吸去离子水720g/g,自来水240～250g/g,0.9%NaCl溶液50～55g/g。Under the action of ammonium persulfate as the initiator,we synthesize super water absorbent contained potassium by graft copolymerizing starch with sodium acrylate and potassium acrylate first,and then ,ammonia is used to neutralize the rest of carboxyl of crylic acid.Finally,we get the super water absorbent contained potassium and nitrogen.Through experiments,we discuss the influence of the properties of sidium acrylate and potassium acrylate and the neutralized degree of crylic acid by ammonia on water absorbent.
