摘要: 近年来通过非冠醚单体的聚合以合成聚合物冠醚,国内外都有一些新的进展.环氧化合物开环聚合时可得到具有乙撑氧链的聚醚,我们选用含环氧基团的化合物作为聚合单体,同时在环氧基团上又引入另外的乙撑氧链,经过开环聚合得到相应的梳形聚醚的主链和侧链都含有乙撑氧链,具有开链冠醚的结构特点,尚未见报道.

关键词: 梳形聚醚, 络合性能, 相转移催化

Abstract: The synthesis and properties of two comb polyethers are reported. Ethylene glycolmonoethyl ether glycidyl ether or diethylene glycol monoethyl ether glycidyl ether werepolymerized in the presence of (i-Bu)3Al catalyst system, giving corresponding comb po-lyethers. They showed good complexing capacities for K+, Na+ and PTC activities for thenucleophilic substitution of BuBr by PhOK.

Key words: Comb polyether synthesis, Complexing capacity, Phase transfer catalysis
