摘　　要：以丝瓜络为原料制备羧甲基纤维素钠,进而与丙烯酸接枝共聚制备出高吸水性树脂。分析了丙烯酸用量、交联剂用量、引发剂用量、单体中和度和反应温度等因素对高吸水性树脂性能的影响,并用红外光谱对产物的结构进行了表征。结果表明:合成的高吸水性树脂的吸水倍率达1500g·g-1,在质量分数为0.9%的食盐水中的吸液倍率达115g·g-1。Sodium carboxymethylcellulose（CMC） was prepared with luffa sponge fiber firstly and then the superabsorbent resin was producted by graft copolymerization with acrylic acid. Effect factors such as the amount of acrylic acid, the content of initiator, the cross linker, the neutralization of acrylic acid and the reaction temperature on the water absorption behavior of the resin were analyzed and the structure of the copolymer was characterized by infrared spectroscopy. Under this conditions, the highest water absorbency of the resin for distilled water and 0.9%NaCl solution were 1500g·g^-1 and llSg·g^-1 respectively.
