| 摘 要： | 通过聚苯乙烯树脂与冠醚二苯并－１８－冠－６间接枝一种含有（－ＣＨ２ＣＨ２Ｏ－）醚链的缩乙二醇（乙二醇，一缩二乙二醇，二缩三乙二醇，三缩四乙二醇）。合成了四种聚苯乙烯支载缩乙二醇二苯并－１８－冠－６的高聚物支载冠醚，均可作用相转移催化剂。聚苯乙烯支载缩二醇二苯并－１８－冠－６催化ｎ－溴辛烷与钾及苯酚钾的取代反应时，活性较未支载二苯并－１８－冠－６为高。

| Abstract: | In this paper, four ploymer_supported crown ethers of polystyrene_supported condensed ethylene glycol dibenzo_18_crown_6 is first synthesized by grafting a contan ether chain ( CH 2CH 2O ) condensed ethylene glycol (ethylene glycol, dicthylene glycol, triethylene glycol, tetraethylene glycol)between polystyrene rasin and crown ether dibenzo_18_crown_8.These supported crown ether can be used as phase transfer catalysts the activities of which in catalyzing the substitution reactions of n _octyl bromide with polassium jodide and phenoxide are greater than that no_supported dibenzo_18_crown_6 |

| Keywords: | polystyrene condensed ethylene glycol crown ether compounds phase transfer catalysis |
