| 摘 要： | 以丙烯酸(AA)、丙烯酸盐和马来酸酐(MA)为原料，过硫酸铵(APS)为引发剂，N,N-亚甲基双丙烯酰胺(MBA)和甘油为交联剂，采用水溶液聚合法合成了一种新型的高吸水树脂. 考察了交联剂用量、引发剂用量以及马来酸酐氨化程度对高吸水树脂吸水性能的影响，并通过正交实验优化了条件，使合成的高吸水树脂对去离子水和0.9%的NaCl水溶液的吸收能力分别达到1689 g/g和115 g/g.

| Abstract: | A kind of novel copolymer superabsorbent resin based on the monomersmaleic anhydride (MA), acrylic acid (AA) and its salts] was prepared by solution polymerization using ammonium persulfate (APS) as initiator, N,N-methylenebisacrylamide (MBA) and glycerine as cross-linking agents. Effects of process parameters such as the concentrations of monomers, cross-linker, initiator and degree of ammoniation of maleic anhydride on the absorbency of superabsorbent resin were discussed. Under the optimal conditions, the absorbency of water from distilled water and 0.9% NaCl solution was 1689 g/g and 115 g/g, respectively. |
