采用水溶液聚合法,制备了羧甲基纤维素/壳聚糖(CMC/CTS)高吸水性树脂。考察了CMC/CTS比值(质量比)、甘油质量、聚乙二醇质量及反应温度等各因素对产物吸水性能的影响,并通过正交试验,确定最佳的合成条件。采用红外光谱对产物结构进行分析。结果表明,高吸水性树脂的最佳合成条件为CMC/CTS为3:1、甘油为1.60g、聚乙二醇为3.20g、反应温度为25℃时,其吸水率为405g·g^-1,且吸水速率适中,保水性能良好,是一种环境友好型高吸水性树脂。
採用水溶液聚閤法,製備瞭羧甲基纖維素/殼聚糖(CMC/CTS)高吸水性樹脂。攷察瞭CMC/CTS比值(質量比)、甘油質量、聚乙二醇質量及反應溫度等各因素對產物吸水性能的影響,併通過正交試驗,確定最佳的閤成條件。採用紅外光譜對產物結構進行分析。結果錶明,高吸水性樹脂的最佳閤成條件為CMC/CTS為3:1、甘油為1.60g、聚乙二醇為3.20g、反應溫度為25℃時,其吸水率為405g·g^-1,且吸水速率適中,保水性能良好,是一種環境友好型高吸水性樹脂。

Carboxymethyl cellulose and chitosan (CMC/CTS) superabsorbent resin were prepared by aqueous solution polymerization. The effects of the ratio of CMC/CTS, the amount of glycerol, the amount of polyethylene glycol and the reaction temperature on the swelling ratio of the resin were discussed. Orthogonal experiments were conducted to determine the best synthetic conditions. The structure of the resin was analysed by FT-IR. The results showed that the optimum reaction conditions were as follows: the ratio of CMC/CTS was 3:1; the amount of glycerol was 1.60 g; the amount of polyethylene glycol was 3.20 g; the reaction temperature was 25℃. And under the above conditions the swelling ratio of the resin was 405 g·g^-1. The water absorption rate was moderate and water-retention ability was good. It is a kind of environmental friendly superabsorbent resin.
