网状聚合物冠醚的合成与性能Ⅰ.以双环氧丙基醚、乙二醇双环氧丙基醚及多缩乙二醇双环氧丙基醚为原料合成
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。

SYNTHESES AND PROPERTIES OF NETWORK POLYMERIC CROWN ETHERS Ⅰ. FROM BISGLYCIDYL ETHER,ETHYLENE GLYCOL BISGLYCIDYL ETHER OR DI(OR TRI, TETRA) ETHYLENE GLYCOL BISGLYCIDYL ETHER
Abstract:
The synthetic method and properties of a series of new network polymeric crown ethers were reported in this paper. Eight network polymeric crown ethers were prepared by the net-polymerization of bisglycidyl ether, ethylene glycol bisglycidyl ether, diethylene glycol bisglycidyl ether triethylene glycol bisglycidyl ether and tetraethylene glycol bisglycidyle ther in the presence of BF3·OEt2 or (i-Bu)3Al as catalyst. The studied network polymeric crown ethers have good cation-complexing ability and effective catalytic activity in the nucleophilic substitution of PhOK with n-BuBr.
