摘　　要：用自行合成的带有可聚合活性基团的硫杂杯芳烃衍生物,分别与苯乙烯和甲基丙烯酸甲酯聚合,得到不同组成配比的两类七种新共聚物。用红外、元素分析和GPC等方法对共聚产物进行了表征,并用液膜传输的方法对共聚物传输铅离子的能力进行了初步研究。结果表明,硫杂杯芳烃衍生物与苯乙烯或甲基丙烯酸甲酯的共聚物均具有较强的铅离子传输能力,是一种新型的功能高分子材料,有望在许多方面得到应用。In this paper, a thiacalixarene derivative with active double-bond was synthesized, and which was as a monomer copolymerized with other monomers by solution polymerization, yield 7 new copolymers. The copolymers were characterized by IR, EA and GPC. The copolymer＇s ability to transport lead ions was shown by use of supporting liquid membrane transport. The results indicate that all the seven thiacalixarene-containing copolymers exhibit the obvious a- bilities to transport lead （ Ⅱ ） ions which are due to the introduction of thiacalixarene to the copolymers. The higher thiacalix[4] arene-content in the copolymers, the higher the transport percent of copolymers to transport lead（ Ⅱ ） ions. They are expected to be used as new functional polymer materials.
