A method is proposed for producing a deposited catalyst for the polymerisation of ethylene and copolymerisation of ethylene with alpha-olefins. The method involves the reaction of a solution of an organomagnesium compound of composition MgPh2.nMgCl2.mR2O (wherein n=0.37-0.7; m≥2, R2O is a simple ether, Ph is C6H5) with a carbon tetrachloride, at a molar ratio of CCl4/Mg ≥0.5 and a temperature of -20 to 60 °C.
