摘　　要：采用反相悬浮聚合法合成聚丙烯酸钠，调节油水两相体积比，添加高岭土和交联剂进行反应，制得高吸水性复合树脂。该树脂２ｍｉｎ内的吸水率为１５００ｇ／ｇ，在０．９％ＮａＣｌ水溶液中的吸水率为１４８ｇ／ｇ，在２５～９０℃内吸水率仍可保持１５００ｇ／ｇ，且该树脂的经时稳定性好。The super absorbent complex resin of polyacrylic acid sodium salt,which was synthesized by means of inverse suspension polymerization,was modified in the present of kaolin and cross-linking agent in the organic solvent consisting of water.The absorption of the resin is 1500g/g for two minutes and 148g/g in case of deionizing water and 0.9%NaCl solution,respectively.In 25～90℃ the absorption of the resin is about the same.
