The synthesis of a benzo‐15‐crown‐5 functionalized α‐olefin (4′‐(undec‐10‐enylcarboxylate)benzo‐15‐crown‐5, 5 ) and its terpolymerization with carbon monoxide and various α‐olefins are described. A decline of the glass transition temperatures ( T g ) of the corresponding terpolymers was observed upon incorporating compound 5 into the polymer main chain. Ion‐selective membranes were prepared by encapsulating the benzo‐15‐crown‐5 functionalized α‐olefin/CO terpolymers in a microporous polyethylene support. Preliminary ion‐transport experiments demonstrate the ability of these novel crown ether substituted polyketones to transport NaClO 4 across the membranes. Adjusting the polarity of the polyketones via the length of the olefinic side chain offers a means to control the ion‐permeation‐rates.
