【摘要】 本文报道了一类新型网状聚合物冠醚的合成方法及其性能。分别通过双环氧丙基醚、乙二醇双环氧丙基醚及多缩乙二醇双环氧丙基醚等五种双环氧单体的网化聚合,直接合成了八种网状聚合物冠醚。聚合反应中分别采用了两种催化体系:BF₃·OEt₂和（i-Bu）₃Al。测定了网状聚合物冠醚对金属阳离子的络合容量及其在亲核取代反应中的相转移催化活性。实验表明,这类网状聚合物冠醚合成简便、性能良好且便于重复使用。更多还原

【Abstract】 The synthetic method and properties of a series of new network polymeric crownethers were reported in this paper. Eight network polymeric crown ethers were preparedby the net-polymerization of bisglycidyl ether, ethylene glycol bisglycidyl ether, diethy-lene glycol bisglycidyl ether triethylene glycol bisglycidyl ether and tetraethylene glycolbisglycidyle ther in the presence of BF₃·OEt₂ or （i-Bu）₃Al as catalyst. The studiednetwork polymeric crown ethers have good cation-complexing ability and effectivecatalytic activity in the nucleophilic substitution of PhOK with n-BuBr.更多还原
