| 中文摘要: |
| 以丙烯酸（AA）为主要单体、过氧化氢 抗坏血酸为引发体系、甲基丙烯酸缩水甘油酯（GMA）为改性单体合成改性吸水树脂，考察GMA/AA摩尔比对改性吸水树脂及相应吸水膨胀橡胶性能的影响。结果表明：GMA改性对吸水树脂及相应吸水膨胀橡胶的吸水性能有较大影响；当GMA/AA摩尔比为0.02时，吸水膨胀橡胶综合性能最佳，且吸水膨胀过程中吸水树脂析出情况得到明显改善。 |
| 英文摘要: |
| Using acrylic acid （AA） as main monomer，H2O2 vitamin C (Vc）as initiation system，and glycidyl methacrylate（GMA）as modification monomer，the water absorbent resin was synthesized，and the effect of mole ratio of GMA/AA on the properties of modified water swellable rubber was studied.The results showed that，the effects of GMA modification on the water absorbent resin and its water swellable rubber were significant.When the mole ratio of GMA/AA was 0.02，the comprehensive properties of the water swellable rubber were the best，and the separation of water absorbent resin from rubber in water swelling process was reduced. |
