Macroporous copolymers of poly(acrylonitrile-co-divinylbenzene) were synthesized in the presence of 2-ethyl-1-hexanol (2 EH) and toluene as diluents. The copolymers were characterized by acrylonitrile content and from morphological point of view. Samples with a minimum content of homopolymer were transformed into weak base anion exchangers by the aminolysis-hydrolysis reaction of the nitrile groups with N,N-dialkylaminoalkylamines. The reactions were investigated by the exchange capacity variation and IR-spectral analysis. It was emphasized that the reactivity of asymmetrical diamines depends on the nucleophilicity of the primary amine group.
