-
Nine phenolic polycondensates with crown ethers were prepared by the condensation of 2,6-dihydroxymehtyl-4-methyl phenol (or 2,6-dihydroxymethyl-4-sulfo phenol) withd1benzo-18-crown-6(2B18C6),dibenzo-24-crown-8(2B24C8),benzo-15-crown-5(B15C5),benzo-18-crown-6(B18C6) respectively,and characterized by IR,1H NMR and DSC.The polymeric crown ethers can be used as complexing resins to enrich cations and as stationary phase in gas chromatography for separation of mixed organic compounds.
