摘要：
The formation of alumina particles from aluminum salts in the presence of poly(1-vinylimidazole) was investigated by quantitative Al-27 NMR, potentiometry and FTIR spectra. The interaction of poly(1-vinylimidazole) with aluminum chloride and nitrate in an aqueous medium stabilizes [AlO4Al12(OH)(24)](7+) and less ordered polymeric particles. The addition of NaOH ( NaOH: Al greater than or equal to 2) results in water-insoluble organic/inorganic hydrogen-bonded composites. Stabilization of the complexes is realized by cooperative hydrogen N...H-O-Al bonds, without N --> Al donor-acceptor interactions.
