In this work we present the data on the formation and composition of new supported catalysts for ethylene polymerization, prepared by interaction of Fe(II) bis(imino)pyridyl complex (LFeCl2) with silica, modified by introduction of alumina compounds (SiO2(nAl)) for generation of Lewis acidic sites (LAS) on the silica surface. Data on the content of LAS with different acidity in SiO2(nAl) supports and on the interaction of LFeCl2 with these sites were obtained. It was found that interaction of LFeCl2 with the most acidic sites of SiO2(nAl) supports leads to formation of the most active catalysts for the ethylene polymerization. © 2020
