本文介绍了在阴离子多糖存在下，通过阳离子甲基丙烯酸酯单体的自由基聚合制备多糖-聚甲基丙烯酸酯杂化材料。特别地，公开了由羧甲基纤维素（CMC）和阳离子聚甲基丙烯酸酯，即聚（甲基丙烯酸2-氨基乙酯）组成的杂化材料的合成。通过甲基丙烯酸2-氨基乙酯盐酸盐（AEMA-HCl）在CMC水溶液中的自由基聚合实现了材料的形成。通过红外光谱和元素分析确定了其结构为CMC和聚甲基丙烯酸酯组成的不溶性物质。进行热重分析（TGA）和差示扫描量热法（DSC）等热分析以确认材料的网络结构。通过在200°C下加热材料发生脱水酰胺化，产生通过酰胺键杂化的新杂化材料。版权所有© 2007约翰威利父子有限公司。
This article describes preparation of polysaccharide–polymethacrylate hybrid materials by means of free-radical polymerization of a cationic methacrylate monomer in the presence of anionic polysaccharides. In particular, synthesis of the hybrid material composed of carboxymethyl cellulose (CMC) and a cationic polymethacrylate, i.e. poly(2-aminoethyl methacrylate) is disclosed. The formation of the materials was achieved by radical polymerization of 2-aminoethyl methacrylate hydrochloride (AEMA-HCl) in aqueous solution of CMC. The insoluble material was formed and the structure was determined by the IR spectra and elemental analysis to be composed of CMC and polymethacrylate. Thermal analyses such as thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) were performed to confirm the network structure of the material. The dehydrative amidation occurred by heating the material at 200°C, giving rise to the new hybrid material hybridized by the amide linkages. Copyright © 2007 John Wiley & Sons, Ltd.
