苯二酚二环氧丙基醚聚合物的合成与性能

Synthesis of bis(epoxypropyl)phenolic ether polymers

分别采用邻、间、对苯二酚和环氧氯丙烷为原料,合成了三种苯二酚二环氧丙基醚新单体,再分别与1,2二氯乙烷聚合,得到三种网状假冠醚聚合物.这些聚合物含有假冠醚结构单元,配合容量在1.73～2.64mmol/g之间,可作为配合树脂使用,富集分离多种金属离子.

In the meantime,three kind of bis(epoxypropyl) phenolic ether monomers were synthesized by the reaction of epichlorohydrin with catechol,resorcin and hydroquinone respectively.And three kind of network polymeric pseudocrown ethers containing oxyalkyl chainring structure were synthesized by the ringopening polymerization of monomers.The results show that complexing capacity of these polymers is in the rang of 1.73~2.64 mmol/g,and the polymers can be used as complexing resin for enrichment of multiform metal ion.
