摘　　要：以咖啡因为模板 ,MAA为功能单体 ,EGDMA为交联剂 ,采用本体聚合方式在不同溶剂中合成了一系列咖啡因分子模板聚合物 .采用紫外分光光度法测定了其对模板分子的吸附性能及其对相似物质的选择性能 .讨论了溶剂种类、搅拌时间及介质的酸碱性对聚合速度及聚合物性能的影响 .与非模板聚合物相比 。A series of polymers were prepared in different solvents using caffeine,methacrylic acid and ethylene glycol dimethacrylate as the template molecule,functional monomer and cross-linking monomer,respectively.A number of preparation parameters were examined by ultraviolet (UV) spectroscopy,including the kinds of solvent used for reaction,equilibration time and the media in terms of the selectivity and capacity of the bulk polymer obtained.The study revealed that both the rate of the polymerization and the characteristic of recognition for the substrate were affected by the porogen.The polymer obtained in acetonitrile gave the optimum selectivity and capacity for caffeine.
