| 摘 要： | 以PVA为原料,用顺丁烯二酸酐作交联剂制得了PVA类高吸水性树脂.研究了交联剂用量、反应温度、PVA聚合度以及处理产物的溶液pH值对树脂吸水率的影响.得到的最佳制备条件为:ω(顺丁烯二酸酐/PVA)为30%,反应温度在98～105℃,所用PVA的聚合度为1700,处理产物的溶液pH值为10左右.

| Abstract: | PVA super absorbent resin was prepared by PVA using maleic anhydride as a crosslinking agent. The influences of amount of crosslinking agent, reaction temperature, PVA polymerization degree, pH of solution on water absorbency were in-vestigated. The optimum reaction conditions were that the ration between rnaleie anhydride and PVA was 30% the reaction tem-perature was 98～105℃, the polymerization degree of PVA was 1700, the pH of solution was about 10. |
