用乙二醇和一缩二乙二醇双环氧丙基醚与甲基、戊基和芐基环硫丙基醚二元共聚的方法,制备了六个新型的网状硫杂聚合物冠醚。用红外光谱、元素分析、差热分析、扫描电镜和电子探针等实验方法对其结构进行了研究。结果表明,这类聚合物冠醚对钠、钾离子有很强的络合能力,并有良好的相转移催化活性。 Six novel net-shaped thia polyether crown ethers were prepared by the binary copolymerization of ethylene glycol and diethylene glycol diglycidyl ether with methyl, pentyl and benzyl epithiopropyl ether . Its structure was studied by means of infrared spectroscopy, elemental analysis, differential thermal analysis, scanning electron microscopy and electron probe. The results show that the polymer crown ether has a strong ability to complex sodium and potassium ions and has good phase transfer catalytic activity.
