网状聚合物冠醚的合成与性能——Ⅲ.乙二醇和一缩二乙二醇双环氧丙基醚与烷基环硫丙基醚的共聚

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。

NETWORKLIKE CROWN ETHER POLYMERS——Ⅲ. Copolymerization of Bisglycidyl Ether with 2-Alkoxymethylthiirane

Six new networklike thiacrown ether polymers (NTCPs) were synthesized by a new method, which is the copolymerization of ethylene glycol bisglycidyl ether or diethylene glycol bisglycidyl ether with 2-alkoxymethylthiiranes. The structure of these polymers was studied with IR, DTA, elemental analysis and scanning electron microscope. It is shown that these polymers have very high complexing capacities with potassium and sodium ions and have good phase transfer catalysis activity.
