摘　　要：以丙烯酸和丙烯酸钠聚合性单体为主要成分，在疏水性溶剂环己烷中经反相悬浮聚合反应制备了高吸水性聚丙烯酸钠。该高吸水性聚合物，不仅对纯水，而且对生理盐水、人造尿等各种电解质水溶液也具有很强的吸水能力，并具有良好的凝胶强度及适宜的发粘感。同时也探讨了吸水机理以及各种因素对高吸水性树脂吸水倍率的影响。A method was introduced to make a high water - absorbing polyacrylic sodium from the monomer sodium acrylate as main component, in presence of cross - linking and initiator by reverse emulsion ploymerization. This production has properties of very high capacity for absorbing pure water and electrolyte solutions such as normal saline, artificial urina. Also, it has good gel intensity, suitable flow resistance. The mechanism of water - absorbing and the influence factors on the water -absorbing capacity were also discussed in this paper.
