【摘要】 以氢氧化钠 /尿素 (NaOH/Urea)水溶液为纤维素溶剂 ,进行了纤维素均相接枝丙烯酸制备高吸水材料的研究。该吸水材料吸去离子水达 4 0 0多倍、自来水达近 2 0 0倍。讨论了纤维素在NaOH/Urea水溶液体系中的溶解 ,考察了反应温度、交联剂用量、引发剂用量对接枝产物吸水性能的影响。更多还原

【Abstract】 Superabsorbent polymer which can absorb de-ionized water 400g/g,or running water 200g/g has been prepared by graft copolymerization of acrylic acid(AA) onto cellulose in Urea-NaOH homogeneous system, The influences of some factors such as reaction temperature,the amount of crosslinker and initiator on water adsorption power were studied,and the solution of cellulose in Urea-NaOH aqueous is also discussed.更多还原
