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。Using acrylic acid（AA） as main monomer,H_2O_2-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 waterabsorbent resin from rubber in water swelling process was reduced.
