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。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。
The direct synthesis of polymer crown ethers by non-crown ether monomers is a notable new way. Mathias et al by cyclopolymerization of α, ω-tetraglycerol bis-vinylether, cyclization of 1,2- [2- (2,3-epoxypropoxy) ethoxy] benzene by Yokota et al. Polymerization respectively synthesized the corresponding linear polymer crown ether. We have synthesized eight novel network polymer crown ethers by cross-linking polymerization of bisglycidyl ether, ethylene glycol diglycidyl ether and polyethylene glycol diglycidyl ether respectively. In order to distinguish from the cyclopolymerization route employed by Yokota et al., We call this polymerization route a networked polymerization and refer to them as reticulated polymer crown ethers according to the structural characteristics of the polymers obtained.
