一种海藻酸盐-聚甲基丙烯酸酯。以阳离子甲基丙烯酸酯单体2-氨基乙基甲基丙烯酸酯盐酸盐为原料，在海藻酸钠存在下进行自由基聚合，制备了杂化材料。随着聚合反应的进行，形成了不溶物质。产物的结构经红外光谱、元素分析和酸解实验确定为由海藻酸盐和聚甲基丙烯酸甲酯组成。产物的TG和DSC数据与海藻酸钠和聚甲基丙烯酸2-氨基乙酯盐酸盐的混合物不同。此外，甲基丙烯酸酯单体在海藻酸钠存在下聚合，然后挥发溶剂，即可形成杂化材料的薄膜。(C)2005爱思唯尔有限公司。保留所有权利。
An alginate-polymethacrylate. hybrid material was prepared by radical polymerization of a cationic methacrylate monomer, i.e. 2-aminoethyl methacrylate hydrochloride in the presence of sodium alginate in water. The insoluble material was formed with progress of the polymerization. The structure of the product was confirmed by the IR spectrum and elemental analysis, as well as the acid hydrolysis experiment to be composed of alginate and polymethacrylate. The TG and DSC data of product were different from those of a mixture of sodium alginate with poly (2-aminoethyl methacrylate hydrochloride). Furthermore, the films of the hybrid materials could be formed by means of the polymerization of the methacrylate monomer in the presence of sodium alginate, followed by the evaporation of the solvent.
