摘　　要：以溶剂萃取的方法研究了癸二酸-二苯并-18-冠-6共聚物（CEP－1）的离子络合效率和选择性，测定了苦味酸盐在水与二氯甲烷中的平衡浓度，求得了草取平衡常数，并与其小分子模型物及酚醛树脂型冠醚聚合物（CEP-2）作了对比。结果表明，酮型冠醚聚合物虽然在离子萃取能力上有所下降，但其对K+却显示出更大的选择性。The efficiency and selectivities in binding cations of ketonic type crown ether polymers (CEP-1 ) were studied by using data obtained from salt distribution equilibria in water-methylene chloride, and were compared with phenolic type crown ether polymers (CEP-2) and their monomer analogs. The results indicated that CEP-1 had higher selectities to K+ than CEP-2 and DB-18-C-6 did, although their binding efficiency was lower than the latter.
