摘　　要：对不同化学组成的保水剂基本性能进行研究的结果表明,淀粉-丙烯酸枝共聚物有较快的吸水速率,聚丙烯酸盐保水性能较好,丙烯酸-丙烯酰胺共聚物有较强的抗盐感性能。The composition and characteristics of water retentive agents (super water absorbent resins) were studied. The results showed that the starch graft polyacrylic acid absorbed water fast, the water retentive capacity of polyacrylic acid (salt) was the best and the absorption amount of polyacrylic-acrylamide was higher than those in case of ionogen water.
