| 摘 要： | 以AA(丙烯酸)、HMAC(羟丙烯酰胺基己基氯化铵)为原料，NMBA(N，N-亚甲基双丙烯酰胺)为交联剂，通过溶液聚合制得低阳离子度交联聚丙烯酸高吸水性树脂，研究了影响高吸水树脂性能的因素，并考察了其在去离子水中和NaCl、CaCl2、MgCl2溶液中的吸水性，以及高温高压下高吸水树脂的保水性。结果表明，加入HMAC阳离子单体，高吸水树脂的耐盐性增加，初始吸水速率增加，饱和吸水率下降，且高温高压下保水性增强。

| Abstract: | The cross - linking polyacrylic acid with a little cationic monomer as superabsorbent resins were prepared by solution polymerization of AA, HMAC and NMBA, and the factors affecting their performance were investigated. Water - holding performance under high temperature and pressure were investigated. The results showed that earlier absorbency rate and water - holding performance increased, saturation absorbency decreased after HMAC added. |
