Abstract: A kind of novel copolymer superabsorbent resin based on the monomers[maleic 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.
Key words: superabsorbent resin, acrylic acid, maleic anhydride, solution polymerization
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.
