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
