Poly-4-vinylpyridine was almost quantitatively quaternized with benzyl chloride in an aqueous ethanol solution, followed by crosslinking before and after immobilization with transition metal ions (Ni, Mn). The obtained samples were studied by physicochemical methods (scanning electron microscope (SEM), x-ray phase (XPA), infrared spectroscopy (IR) analysis. The aim is to use quaternized, cross-linked and immobilized samples as an effective sorbents and catalysts in many chemical processes.
