✦ Synopsis
The products of the chemical modification of e,o)-dichloropoly(oxyethylene) (molecular weight of the polyether chain 200, 400 and 1000) with potassium 5-nitro-8-quinolinolate have been studied. Their structures have been established by u.v. and IH-NMR spectroscopy. Additional evidence for the formation of poly(oxyethylene)s with 5-nitro-8-quinolinolate end-groups is provided by the similarity in the absorption spectra of the products and the model compound (5-nitro-8-ethoxyquinoline).
