摘　　要：采用反相悬浮聚合法合成丙烯酸－丙烯酰胺共聚物，调节油水两相体积比，添加高岭土和交联剂进行交联反应，制得高吸水性树脂。该树脂吸水率较高，吸水速度快，３—５分钟可达饱和吸水量，耐盐性好，具有较好的热稳定性。The super water absorbent complex resin of poly(acrylate-co-acrylamide), which was synthesized by means of inverse suspension polymerization,was modified in the presence of kaolin and cross-linking agent in the organic solvent containing water. The water absorption of the resin for three minutes is 94% of the saturation value. The factors of influence on absorbency have been studied.
