Aqueous radical addition-coupling polymerization for the synthesis of hydrophilic periodic polymer†
Abstract
A hydrophilic polymer possessing a [ABxAC]n (A = ester, B = ethylene oxide, C = N–O) repeating sequence was synthesized by an aqueous radical addition-coupling polymerization using water-soluble dibromide and a nitroso compound in the presence of a CuBr/ligand. This opens up a new pathway to synthesize water-soluble periodic polymers with a regular sequence.
