摘　　要：采用溶液聚合法合成了木薯淀粉接枝丙烯酸盐吸水剂,研究了原料配比、引发剂和交联剂等工艺条件对聚合产物性能的影响,并探讨了原料配比对产物生物降解性的影响。实验结果表明,在中和度为80%,引发剂量为单体量的0.2%,交联剂量为单体量的0.1%,木薯淀粉与丙烯酸的质量比为1∶3,在70℃下反应4h条件下,所制得吸水剂的吸水倍数及生物降解性能为最优。A starch-sodium acrylate graft absorbent was synthesized by means of aqueous solution polymerization. The effects of starch content,initiator content ,crosslinker content on the characteristics of products as well as the effects of starch content on the biodegradablitis of products were investigated. When the reaction conditions were 70℃ ,4hour reaction time,80% neutralization degree（ND） of acrylic acids,0. 20% initiator and 0. 10% crosslinker on the basis of the mass of acrylic acid used, it had a high water absorbency and a better biodegradation.
