【Abstract】 A superabsorbent polymer,cross-linking sodium polyacrylate was synthesized with a novel method initiated at low temperature and polymerized and desiccated at high temperature.The factors influenced the superabsorbent properties,such as initiation temperature,polymerization and desiccation temperature,the concentration of monomer,initiator and cross-linker,and the degree of neutralization were investigated.The experimental results showed that this superabsorbent not only had high water absorbency but excellent hydrogel strength.更多还原
