SYNTHESES AND PROPERTIES OF COPOLYCONDENSATES OF PHENOLICS AND CROWN ETHERS
冠醚共缩聚物的合成与性能（Ⅱ）

Eight new polycondensates of phenolics and crown ethers are preparedby the condensation of 2,6-dihydroxymethyl-4-methylp (or4-sulfophenol) withdibenzo-18-crown-6 (2B18C6), dibenzo24-crown-8 (2B24C8),benzol 5-crown-5(B15C5),benzols-crown-6(B18C6) respectively and charaterized by IR HNMR DSC.The polymeric crown ethers can' be used as complexing resin to collect differentionsand as stationary phases in gas chromatography for separation of mixed organiccompounds.
