Abstract
Acryloyl methyl benzo-18-crown-6 monomer was synthesized by reacting 4''-hydroxymethyl benzo-18-crown-6 with acryloyl chloride. The homopolymer of acryloyl methyl benzo-18-crown-6 was prepared in benzene by using AIBN as an initiator. Cation flux values were determined using a H2O-CH2Cl2-H2O liquid membrane system for alkali metal ions, alkaline earth metal ions and Pb2+ cation. Both monomer and polymer of liquid phase were used as carriers. In binary transport, these ligands demonstrate effective transport selectivity for Pb2+ion. Transport behavior in these single and binary systems can be predicted from Mn+-polyether complex.

Acryoyl methyl benzo-18-crown-6 단위체는 4''-hydroxymethyl benzo-18-crown-6와 acryoyl chloride를 반응시켜 합성하였다. Acryoyl methyl benzo-18-crown-6의 단폭중합체를 벤젠용매하에서 AIBN를 개시제로 하여 제조하였다. 양이온 Flux값들은 알칼리 금속이온속이온, 알칼리 토금속이온, 납이온을 H2O-CH2C12-H2O 액체막계를 이용하여 결정하였다. 단량체와 단독중합체를 리간드 운반체로 사용하였다. 경쟁이동에서 이 리간드가 Pb2+에 대해서 매우 효과적인 선택성을 보이고 있다. 단일계와 경쟁계에서 이동현상을 Mn+-polyether착물로 부터 예상을 할 수가 있다.
