摘　　要：2,4,6-三羟甲基苯酚与单苯并冠醚和二苯并冠醚在强酸催化下缩聚合成了5种新酚醛型冠醚聚合物。对其溶解性和溶胀性、热稳定性、配位性能和富集效率进行了研究。其动态富集容量为0.137mmol/g。可用于多种金属离子的富集分离。Five new polymeric crown ethers have beensynthesized by the condensation of 2,4,6-tri-hydroxymethylphenol and benzocrown ethers in thepresence of formic acid and inorganic acid suchas H_2SO_4(98%).The new method can be usedin production.The complexing capacity,enrich-ment efficiency for metallic ions and the ther-mostability of the polymeric crown ethers havealso been investigated.The results indicate thatall the polymers can be used under 185℃ and theenrichment efficiency of P2B18C6 for Ag^+,K^+and Cu^(2+)(10^(-6)～10^(-3)mmol/mL)reaches 100%,higher than that of the products synthesized byprevious condensation methods.
