摘要: 探讨了在高单体浓度丙烯酸钾下制备自交联型超强吸水剂的可行性，通过加料方式及配方的改进，使反相悬浮聚合得稳定进行，并得到了性能优于低单体浓度下制得的吸水剂。其吸水（去离子水）倍数达到１２００－１４００ｇ／ｇ吸０．９％生理盐于１２０－１５０ｇ／ｇ。Abstract: superabsorbent was prepared at a monomer concentration as high as 65% to 80%, based on the amount of both potassium acrylate and free acrylic acid. With some feeding skills and improvements on the ingndient, the polymerization was carried out smoothly.The
