Acyclic polyether dicarboxylicacids having butyl and tetradecyl side alkyl chains at the α-position of the carboxylic acid sidearm unit were prepared by the reaction of bisphenol and 2-bromoalkanoic acid in the presence of sodium hydride with quantitative yields. Complexation studies and solvent extraction on complexes of these ethers with alkalineearthmetal ions indicate that 1,2-bis((2-2‘-car
