摘　　要：以N-羟甲基丙烯酰胺(N-MAM)和丙烯酸(AA)为聚合单体,过硫酸铵(APS)和N,N,N′,N′-四甲基乙二胺(TEMED)为引发体系,N,N-亚甲基双丙烯酰胺(MBA)为交联剂采用自由基水溶液聚合法合成了p(N-MAM-co-AA)水凝胶。研究了APS、MBA的用量、单体浓度与单体配比、溶液pH值和温度对水凝胶溶胀性能的影响,同时还研究了凝胶的溶胀-退溶胀动力学。The hydrogel poly（N-MAM-AA）was prepared by radical aqueous solution polymerization method.In this procedure,N-MAM and AA were used as the monomers,MBA was used as the crosslinking agent,and APS and TEMED were used as the initiators.Effects of experimental conditions,including the amount of crosslinking agent and initator,monomer concentration and ratio,pH and temperature,on the swelling property of hydrogel were studied.The dynamics of swelling and deswelling were also studied.
