Some novel copolyethers containing azo benzene chromophors as side chains have been synthesized by a nucleophilicreaction of various azo dyes with polyepichlorohydrin.
Vicarious nucleophilic substitution (VNS) of hydrogen is a new type of reaction which is different from the usual electrophilic and nucleophilic reactions of the nitro arenes.
