| 摘 要： | 研究了聚丙烯酸盐及丙烯酰胺-丙烯酸盐共聚物高吸水性树脂在几种电解质溶液(NaCl,NH4Cl,KCl,CaCl2,BaCl2,CuCl2)中的吸液率.结果表明,吸水树脂的吸液率随NaCl水溶液浓度变化呈幂函数规律;正离子价数相同时,不同电解质对高吸水性树脂吸液率有不同影响,但比离子价数的影响小得多.

| Abstract: | The absorbencies in several electrolyte solutions(NaCl, NH_4Cl,KCl,CaCl_2,BaCl_2,CuCl_2) are studied for super absorbent polymers which include polyacrylates and acrylamide-acrylate copolymer.The results show that the solution absorbency of absorbent polymers presents a changing regularity in a power function with the concentration of NaCl solution.When possessing the same valence number of positive ion,different electrolytes have different effects on absorbencies of super absorbent polymers,but it is much smaller than the effects of ion's valence. |

| Keywords: | super absorbent polymer electrolyte solution absorbency salt-tolerability |
