本文报道了一种合成硫杂冠醚聚合物的新方法。以聚(2′-氯乙基-2,3-环硫丙基醚)为预聚物与二巯基化合物通过大分子反应直接环化,一步法合成了四种以聚硫醚为主链的新型硫杂冠醚聚合物(PD1-PD4)。并测定了它们对Ag~+、Au~(3+)、Pd~(2+)、Pt~(4+)、Cu~(2+)、Hg~(2+)、Zn~(2+)、Cd~(2+)、Pb~(2+)、Mg~(2+)、K~+、Ns~+等金属离子的络合性能。结果表明:它们除不络合K~+、Na~+、Mg~(2+)、Pb~(2+)外,对其它八种离子有不同程度的络合,其中对Ag~+、Au~(3+)、Pd~(2+)等贵金属离子的络合容量较高。
In this paper, a new method of synthesizing thio-crown ether polymers was reported. Poly (2’-chloroethyl-2,3-epithiopropyl ether) as prepolymer and dimercapto compounds were directly cyclized by macromolecule reaction, and four kinds of polysulfide-based Novel thia crown ether polymer (PD1-PD4). The effects of Ag +, Au ~ (3 +), Pd ~ (2 +), Pt ~ (4 +), Cu ~ (2+), Hg 2+, Zn 2+ , Cd ~ (2 +), Pb ~ (2 +), Mg ~ (2 +), K ~ +, Ns ~ + and so on. The results showed that there were different degrees of complexation for the other eight ions except K +, Na +, Mg 2+ and Pb 2+. Among them, Ag +, Au ~ (3 +), Pd ~ (2+) and other precious metal ions higher complex capacity.
