A method is proposed for producing a deposited catalyst for the polymerization of ethylene and copolymerization of ethylene with delta -olefins which 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 DEG to 60 DEG C.
