  • Method of producing a deposited catalyst for the polymerization of ethylene and copolymerization of ethylene with O-olefins
    Patent number: 5696044
    Abstract: 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 MgPh.sub.2.nMgCl.sub.2.mR.sub.2 O (wherein n=0.37-0.7; m.gtoreq.2, R.sub.2 O is a simple ether, Ph is C.sub.6 H.sub.5) with a carbon tetrachloride, at a molar ratio of CCl.sub.4 /Mg.gtoreq.0.5 and a temperature of -20.degree. to 60.degree. C.
