Abstract:It has been established that at low temperatures of TiCl4+AOC catalyst preparation in solution (with Ti/Alsim1/15), ESR spectra exhibit rhombic anisotropy of the g-factor. Experiments with the sample having 61 % concentration of47Ti isotopes suggest the formation of associates of Ti3+ with magnetic ordering, apparently due to the Jahn-Teller cooperative effect.
