摘　　要：由２，６－二羟甲基－４－甲基（或磺酸基）苯酚分别和芳香族冠醚（Ｂ１５Ｃ５、Ｂ１８Ｃ６、ＤＢ１８Ｃ６、ＤＢ２４ｃ８等）在强酸催化剂下缩聚，合成了２个系列冠醚共缩聚物。它们的萃取能力和配合作用均优于相应的单冠醚，并可作为树脂吸附分离多种金属离子，作为配合剂测定钾、钠以及作为气相色谱固定液分离多种有机物。Nine phenolic polycondensates with crown ethers were prepared by the condensa-tion 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. Thepolymeric crown ethers can be used as complexing resins to enrich cations and as stationaryphase in gas chromatography for separation of mixed organic compounds.
