摘要

A hydrophilic polymer possessing a [AB(x)AC](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.
