摘要： 通过非冠醚单体直接合成聚合物冠醚,是一条值得注意的新途径。Mathias等通过α,ω-三缩四乙二醇双乙烯醚[1]的环化聚合,Yokota等通过1,2-[2-(2,3-环氧丙氧基)乙氧基]苯的环化聚合[2]分别合成了相应的线型聚合物冠醚。我们分别通过双环氧丙基醚、乙二醇双环氧丙基醚及多缩乙二醇双环氧丙基醚的交联聚合,合成了八种新型网状聚合物冠醚[3]。为了与Yokota等采用的环化聚合途径相区别,我们称这种聚合途径为网化聚合,并根据所得聚合物的结构特征将它们称为网状聚合物冠醚[3]。

Abstract: A convenient method for the synthesis of network polymeric crown ethers containing side group on network unit starting from non-crown ether monomers has been reported.Thus,six new network polymeric crown ethers have been synthesized by ring-opening copolymerization of ethylene glycol bisglycidyl ether and various monoglycidyl ethers in the presence of ( i-Bu)3Al/H3PO4/H2O/PhN(CH3 )2 as catalyst,respectively.The obtained polymers possess good complexing capacities for sodium and potassium ion and most of them show effective PTCactivity in the nucleophilic substitution of BuBr by PhOKin triphase system.
