摘要
高吸水性树脂（Super absorbent polymet．简称SAP）是一种含有强亲水性基团．并通常具有一定交联度的水溶胀型高分子聚合物，是20世纪60年代开始发展起来的新型功能高分子材料。高吸水性树脂的吸水量大、保水性强，即使在受热加压下也不易失水。随着经济的高速发展和环保意识的增强．高吸水性树脂的应用范围不断扩大．市场需求日益增加．研究开发也日趋活跃。
In this article, the graft copolymerization of acrylic acid, acrylamide and butyl methacrylate onto carboxymethyl cellulose is studied with the aim of synthesizing super absorbent polymer (SAP) , the main purpose is to improve absorbency of SAP by the cooperative action of different kinds of hydrophilic groups. Optimization of synthetic conditions is studied emphatically; and the structure of the product is characterized; besides, absorbency and water retention capability of SAP are also determined. According to the results of SEM, absorbency and water retention capability of SAP are improved greatly because of a lot of crevasse cracks, pores and bedded structure are appeared on the surface of the product. Many property-tests show that good absorbency and water retention capability of SAP are observed.
