Summary
α,ω-bis(p-vinylbenzyl)-terminated oligo(ethylene oxide)s (I) with oxyethylene repeating units of 1–21 were prepared. Suspension copolymerization of I with styrene gave the insoluble crosslinked polymer beads (II) which were found to act as highly effective phase transfer catalysts in the reaction of solid potassium phenoxide with 1-bromobutane in toluene.
