　　分子印迹聚合物吸附选择性好，有利于印迹分子的分离纯化。以蔗糖为模板分子，甲基丙烯酸为功能单体，N，N′-亚甲基双丙烯酰胺为交联剂制备了蔗糖分子印迹聚合物，利用单因素试验考察了不同引发剂、引发剂用量、模板分子与功能单体的用量比、反应温度、反应时间、功能单体与交联剂的用量比对印迹聚合物吸附容量的影响，并用傅立叶变换红外光谱仪（FT-IR）和扫描电子显微镜（SEM）对印迹聚合物的结构进行了分析。实验结果表明，最佳反应条件为：引发剂为过硫酸铵，其浓度为1.2 mg/mL，反应时间18 h，反应温度50℃，甲基丙烯酸与蔗糖的用量比为4∶1，交联剂与甲基丙烯酸的用量比为5∶1。扫描电镜图显示，分子印迹聚合物具有纵横交错的网络和许多特异性识别孔穴。红外光谱表明，印迹聚合物中的模板分子能被很好地洗脱下来。

The molecularly imprinted polymers have been discovered to have good selectivity for ab-sorption .It is beneficial to separation and purification of the imprinted molecule .The molecularly imprinted polymers of sucrose were prepared by using the sucrose as template molecule , methyl methacrylate as functional monomer and N , N′-methylene bisacrylamide as crosslinker .The effects of the different initiators , dosage of initiator , dosage ratio of sugar and methyl methacrylate , reaction temperature , reaction time and the dosage ratio of functional monomer and crosslinking agent on the adsorption capacity of molecularly imprinted polymers were investigated with single factor method . The structure of imprinted polymers was analyzed by IR , SEM.The experiments showed that the op-timal reaction conditions were ammonium persulfate as initiator , its concentration 1.2 mg/mL, the reaction time in 18 h, the reaction temperature at 50℃, the dosage ratio of methyl methacrylate and sugar in 4∶1, and the dosage ratio of crosslinking agent and methyl methacrylate in 5∶1.The SEM results showed that the molecularly imprinted polymers surface appeared crisscross network and many specific identification cavities .The FT-IR results showed that the template molecules in polymer were well eluted down .
