P(AA-AM)/PVP半互穿高吸水性树脂的制备与性能研究
摘 要
高吸水性树脂（SAP）是一种具有一定交联度的多孔三维空间网络结构的新型高分子聚合物，其能迅速吸收比自身高上百倍甚至几千倍质量的液态水, 且在常温下具有良好的保水能力。本文介绍了高吸水性树脂的分类，主要分为淀粉类，纤维素类，合成聚合物类，有机/无机复合系类，并阐述了高吸水性树脂的吸水机理和具有半互穿网络（semi-IPN）结构的一类高吸水性树脂，除此之外还介绍了国内外的研究进展。最后，基于文献总结简述了本课题实验的主要内容、意义目的以及具体的实验方案设计。

Preparation and properties of P(aa-am)/PVP semi-interpenetrating superabsorbent resin
ABSTRACT
Superabsorbent resin (SAP) is a new kind of macromolecule with a certain degree of cross-linking and three-dimensional porous spatial network structure. This paper introduces the classification of superabsorbent resin, which is mainly divided into starch, cellulose, synthetic polymer, organic/inorganic composite series, and expounds the water absorption mechanism of superabsorbent resin and a kind of superabsorbent resin with semi-interpenetrating network (semi-IPN) structure. In addition, the research progress at home and abroad is also introduced. Finally, based on the literature summary, the main content, significance and purpose of the experiment as well as the specific design of the experiment scheme are briefly described.
