Description
Summary:Chemical modification of α,ω-dichloropoly(oxyethylene)s (MW from 400 up to 3000), for obtaining poly(oxyethylene)s with 5-chloro-8-quinolinoxyl end-groups, is described. The products have been characterized by GPC, 1H-NMR and electronic spectra. Their ability to form complexes with polymers of acrylic and methacrylic acids in dilute aqueous solution has been investigated. 5-Chloro-8-quinolinoxyl end-groups stabilize the polycomplexes. It has been shown that, in the polycomplexes, the N-atom from the quinoline group is not protonated. The fact has been explained by the localization of the 5-chloro-8-quinolinoxyl end-groups mainly in the hydrophobic domains of the complexes.
