Mono- and alpha,omega-bis-styryl-oligo(oxyethylene glycol) ethers have been constructed in an efficient two-step synthesis. From these precursors, poly(oxyethylene glycol) polymer (POP) supports of varying monomer and cross-linker composition have been produced. The swelling properties and mass-solvent uptake of these novel materials have been evaluated in a variety of solvents, demonstrating that
New crown ethers, exhibiting high Li+-selectivity on the solid-liquid extraction, were prepared from α,ω-bis(-vinylphenyl)oligo(oxyethylenes) by the title reaction in excellent yields.
