摘要：
A process for producing a polysaccharide superabsorbent particulate including the process steps of bringing into contact a polysaccharide with a polyphosphate or a polyphosphoric acid as crosslinking agent in the presence of water to form a polysaccharide gel drying the polysaccharide gel, comminuting the dried polysaccharide gel to form polysaccharide superabsorbent polymer particles, coating the particles with a polyphosphate or polyphosphoric acid, crosslinking the coated particles, and surface treating the particulate with a metal multivalent salt or an acid. The invention further relates to a polysaccharide superabsorbent polymer particulate obtainable by this process, a water-absorbent polysaccharide, a composite, a process for producing a composite, a composite produced by this process, the use of the polysaccharide superabsorbent particulates or of the composites as well as the use of polyphosphates.一種製造多醣超吸收性微粒之方法,其包括下列程序步驟:令多醣與作為交聯劑之聚磷酸鹽(酯)或聚磷酸在水的存在下接觸以形成多醣凝膠,乾燥該多醣凝膠,粉碎該已乾燥多醣凝膠而形成多醣超吸收性聚合物粒子,以聚磷酸鹽(酯)或聚磷酸塗布該等粒子,交聯該等經塗布粒子並以金屬多價鹽或酸表面處理該微粒。本發明另外關於一種可藉由此方法獲得之多醣超吸收性聚合物微粒、一種吸水多醣、一種複合物、一種製造複合物之方法、一種藉由此方法製得之複合物、該多醣超吸收性微粒或該等複合物之用途以及聚磷酸鹽(酯)之用途。500‧‧‧進行凝膠床滲透率試驗之設備528‧‧‧測試設備套件530‧‧‧樣品容器或樣品杯600‧‧‧溢流口601‧‧‧收集裝置602‧‧‧天平603‧‧‧燒杯604‧‧‧計量泵
