摘　　要：以淀粉和丙烯酸为主要原料通过共聚反应制备淀粉接枝高吸水性树脂,研究了淀粉种类对高吸水性树脂性能的影响,并对高吸水性树脂进行生物降解实验。结果表明,高吸水性树脂的吸水率达到1079g/g,60℃下8h的保水率约为15%,在土壤中35d后其降解率为29%。The super absorbent polymers are prepared through eopolymerization with starch and acrylic acid as the main raw materials. The effects of starch on the performance of super absorbent polymers are studied, and the biology degradation test is carried out. The results showed that the water absorption of starch graft resin is 1079 g/g, the rate of keeping water during 8 h in 60℃ is about 15% , after 35 days the degradation rate is 29%.
