| 摘 要： | 应用两种方法分别制备了两种新的高吸水凝胶。一是 PVA(聚乙烯醇 )与马来酸酐油相酯化反应制备改性 PVA,二是气相悬浮接枝聚合方法制备淀粉接枝聚丙烯酸盐。前者用不同的碱中和可得不同性能的产品 ,后者则是用了一种新的方法制得吸水量达 390 g/g的凝胶

| Abstract: | This paper suported the preparation of two new types of super waterabsorbing gels by two methods, respectively. In one method, modified polyvinyl alcohol(PVA) were prepared by esterification of PVA with maleic anhydride in oil solvent. While in the other method, starch grafted polysodium acrylate were prepared by graft polymerization in gas floatation system. The former could be made into different performence gels by neutralizing it with different base. The latter was obtained by new way, its water absorbency is up to 390g/g. |
