摘　　要：以红薯淀粉为接枝母体,丙烯酰胺和丙烯酸为单体,利用反相悬浮法对红薯淀粉—丙烯酰胺—丙烯酸三元共聚吸水性树脂进行研究。讨论了引发剂用量、交联剂用量、单体中和度、反应时间、反应温度、油水比等因素对树脂吸水率的影响;并对树脂的保水性、耐盐性、再生能力等性能进行研究。The terpolymer absorbent resin, sweet potato starch, acrylamide and acrylic acid, was studied by inverse suspension method with sweet potato starch as graft matrix, acrylamide and acrylic acid as mono- mer. The effects of the factors, such as the amount of initiator, crosslinking agent, and the neutralization degree of monomer, reaction time and temperature, the ratio of oil to water, on the water absorption of the resin were discussed. The performance of the resin, such as water retention, salt tolerance and regeneration capacity were also studied.
