【摘要】 采用微波辐射方法制备了羧甲基纤维素钠（CMC）接枝2-丙烯酰胺基-2-甲基丙磺酸（AMPS）/丙烯酰胺（AM）高吸水树脂。利用傅立叶红外光谱仪对树脂官能团进行了表征。研究了交联剂用量、引发剂用量、单体配比、中和度和微波功率对树脂吸水性能的影响。对树脂在不同盐溶液的吸水性能进行了研究。实验结果表明:最佳合成条件下树脂吸蒸馏水倍率达780g/g,吸0.9%（质量分数）NaCl盐水倍率为83g/g;树脂的吸水倍率随着电解质溶液浓度的增加显著下降,且与阳离子的价态有关,其吸水倍率大小顺序为NaCl>MgCl₂>AlCl₃,表现出价态越高,吸水倍率越低的规律。更多还原

【Abstract】 Carboxymethylcellulose（CMC） grafted 2-acrylamido-2-methyl propane sulfonic acid（AMPS）/ acrylam. de（AM） superabsorbent resin was synthesized by microwave irradiation irradiation and the functional group of resin was charactered by FTIR.The impact factors of synthesizing super absorbent resin such as amount of crosslinker and initiator,the ratio of monomer,neutralization degree and microwave power were discussed. Meanwhile,water absorption of resin in different salt solution was studied.The results showed that under the optimum conditions,the water absorption rate of resin was 780 and 83g/g respectively in distilled water and 0.9 wt%NaCl;however,the absorbency decreases sharply with an increasing of solution concentration,moreover, the water absorption rate have related to the valence of cation,the sequence of water absorption rate was:NaCl>MgCl₂>AlCl₃,indicating that the higher of the valence,the lower of the water absorption rate.更多还原
