中文摘要：

　为了解决现有高吸水树脂（SAP）产品耐盐能力低、生物降解性差的缺点，利用反相悬浮聚合法，将羧甲基纤维素（CMC）与丙烯酰胺（AM）和甲基丙烯酰氧乙基三甲基氯化铵（MAETAC）接枝共聚，创新合成了分子中同时含有阳离子和非离子亲水基团的CMC改性高吸水树脂（ICAM）。对合成反应的影响因素进行了探讨和研究，得出的反相悬浮聚合法制备ICAM树脂的优化工艺条件为油水比2：1，分散剂采用Span60与Tween80复配，二者质量比为3：1，总用量为水相质量的5％，CMC加入量为单体的5％，单体水溶液体系pH值为4，引发剂（NaHSO3、（NH4）2S2O8）用量为单体的2．5％，交联剂N，N＇-亚甲基双丙烯酰胺（NMBA）用量为单体的0．5％，反应温度为65℃，反应时间2h。该条件下得到的树脂产品吸蒸馏水倍率为657g／g、吸0．9％NaCl溶液为116g／g。

英文摘要：

Acrylamide （AM） , and [ 2-（methylacL＇yloyloxy） ethyl] trimethylammonium chloride （MAETAC） were grafted onto carboxymethyl cellulose （CMC） to prepare cellulose-modified cationic superabsorbent polymers （SAP） by inverse suspension copolymerization. Factors affecting water-absorbent capacity were investigated in detail, which were found to be as follows： ratio of oil to water 2：1, dosage of Span 60 andTween 80（3：1）, 5 % of water phase, pH value 4, CMC dosage5 %, content of initiator（ NaHSO3, （ NH4）2S2O8 ）2.5 % , and erosslinking agent 0. 5 % of the weight of monomers, reaction temperature 65 ℃, reaction time 2 h. The cellulose-modified cationic SAPs prepared under optimum conditions were obtained which have the absorbent capacity of 657 times their own weight in distilled water and 116 times in 0. 9 % salt solution under optimized synthesis condition.
