摘　　要：从高聚物化学结构角度出发 ,论述了可生物降解超强吸水剂的结构设计思路 ,并对当前文献报道的天然多糖类聚合物改性法、氨基酸法、蛋白质改性法、天然聚合物与丙烯酸接枝共混法等可生物降解超强吸水剂的制备技术及其优缺点进行了系统归纳和评述 ,在此基础上指出了今后这一领域的研究和发展方向。The thought of structure design of biodegradable SAP is discussed in this paper according to the chemical structure theory of macromolecular polymers. The preparation technology of biodegradable SAP reported in literature, mainly including modification of natural polysaccharides, poly (amino acid)s, proteins from different kinds of animals or plants, as well as graft or blend of poly(acry acid) with natural polymers is reviewed and commented.The pros and cons of the above preparation technology are valued.On the base of the disccusion, the researching directions of this field in the future are pointed out too.
