Dsc for the nanocomposites showed the glass transition temperature ( tg ) of the nanocomposites increases slightly as the mmt content increases . water absorption velocity and water retentivity under pressure tests showed the addition of montmorillonite ( mmt ) can improve the beginning absorption velocity and water retentivity for pure superabsorbent resin 吸水速率和加压保水能力测试表明，一维纳米级蒙脱土片层的引入能在一定程度上提高高吸水性树脂的初期吸水速度和加压下的保水能力。
