超高吸水性树脂的合成研究

Study on synthesis of super high absorption resin

采用丙烯酰胺与丙烯酸 (钠 )共聚体系 ,以过硫酸胺 (NH4) 2 S2 O8为引发剂 ,N ,N—双亚甲基丙烯酰胺为交联剂 ,得到轻度交联的高分子化合物 ,用聚乙烯醇改善其三级结构 ,制得超高吸水剂 ,吸收含 0 .9%的NaCl盐水达自身重量的近百倍 .

The super high absorption resin was derive from the polymerization of AM and AA(or its salt)by using (NH 4) 2S 2O 8 as inicating.The three classes structure of the polymer was modefiled by using PVAL.And the polymer was slight crosslinked by N,N dimethyleneallyamide.The techanology of preperation is simple and the times of absorption water of production reached as 100.
