摘　　要：以N ,N-亚甲基双丙烯酰胺为交联剂 ,过硫酸铵 /亚硫酸氢钠为氧化还原引发剂 ,采用水溶液聚合法合成出高岭土复合聚丙烯酸钠 -丙烯酰胺高吸水性复合树脂。研究了高岭土的添加量对复合树脂的吸水性、吸水速度及保水性等的影响 。A new type of high water-absorbing copolymer resin based on sodium acrylate, acrylamide and N, N-methylene-bis-acrylamide was prepared by water solution copolymerization and with potassium persulfate/sodium acid sulfite as a redox initiator. The effect of the amount of kaolinite on water-absorption capacity, water absorption rate and water retention of copolymer was studied. The water retention and kinetic process of dewatering of the bentonite composite resin was studied by TGA and DSC.
