摘要
以N,N′-亚甲基双丙烯酰胺(NMBA)为交联剂、过硫酸氨(APS)为引发剂,采用丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和马来酸(MA)为单体,在水溶液中合成AMPS-MA-AM三元共聚物。探讨单体比例、温度和反应时间等对共聚物的吸水性能的影响;结果表明:聚2-丙烯酰胺基-2-甲基丙磺酸/马来酸/丙烯酰胺P(AMPS/MA/AM)具有优良的吸水、耐盐性能;在去离子水、生理盐水中吸水倍率可以达到358、135g/g。
The maleic acid（MA）,2-acrylamido-2-methylpropanesulfonic acid（AMPS）and acrylamide（PAMPS/AM/MA）superabsorbent copolymer was synthesized by aqueous solution polymerization with ammonium persulfate as initiator,N,N′-methylene-bisacrylamide（NMBA）as crosslinking agent.The influence of neutralization degree of MA,mass ratio of AMPS to acrylamide（AM）,the amount of crosslinking agent and initiator,and reaction temperature on the absorption capability of water and salt solution were investigated.The results showed that the water absorbency of superabsorbent prepared at the optimum condition in deionized water and in 0.9% NaCl solution was about 358 and 135g/g,respectively.And under the same conditions,the sample had more excellent water absorption and salt-resistance.
