摘　　要：本文以淀粉为骨架 ,丙烯酸、丙烯酰胺为接枝单体 ,过硫酸钾为引发剂 ,采用高温快速聚合的方法进行高吸水性树脂的制备。通过正交实验确定了最优配方 ,产品吸水率达到 15 5 0 g/ g ,吸盐率为 95 g/ g。In this paper,the super absorbent polymer(SAP)was fast polymerized at high temperature with using starch as the skeleton,acrylic acid(AA)as monomers,potassium persulfate(K 2S 2O 8)n as the initiator.The best formula was obtained by orthogonal experiments,and the products exhibited values of 1550 g H 2O/g sample in deionized water and 95 g H 2O/g sample in deionized oater and 95 g H 2O/g sample in 0 9 wt% NaCl solution.
