摘　　要：采用反向微乳液聚合法制备得到交联P(AM-AA)微球,利用正交实验分析了丙烯酰胺(AM):丙烯酸(AA)单体配比、N-N亚甲基双丙烯酰胺(MBA)交联剂用量、过硫酸钠(ASP)引发剂用量及聚合温度对P(AM-AA)微球溶胀性能影响,确定最佳合成条件为:AM:AA质量比为1:1,MBA用量为0.6%,APS加量为0.4%,反应温度为65℃,该条件下所得P(AM-AA)微球溶胀率可达1214.29%。Crosslinked P(AM-AA)microspheres were prepared by reverse microemulsion polymerization.The effects of the ratio of AM to AA,N-N methylene bis acrylamide(MBA)crosslinking agent dosage,sodium persulfate(APS)initiator dosage and polymerization temperature on the swelling properties of P(AM-AA)microspheres were analyzed by orthogonal experiment.The optimum synthesis conditions were AM:AA mass ratio of 1:1,and the MBA dosage of 0.6%.The swelling rate of P(AM-AA)microspheres was 1214.29%under the condition of APS dosage was 0.4%and the reaction temperature was 65℃.
