Aqueous radical addition-coupling polymerization using a nitroso benzene/cyclodextrin complex for the synthesis of a hydrophilic periodic polymer

Abstract

A hydrophilic periodic polymer possessing a [AB_xAC]_n (A = ester, B = ethylene oxide, C = N–O) repeating sequence was synthesized by aqueous radical addition-coupling polymerization using a water-soluble inclusion complex of nitrosobenzene and Me₂-β-cyclodextrin together with poly(ethylene glycol)bis(α-bromoisobutyrate) in the presence of Cu/ligand.
