Abstract
The present invention relates to a method for producing a Ti/V supported catalyst useful in polymerization of ethylene and copolymerization of ethylene and &agr;-olefin. The method includes a treatment, by a titanium compound and a vanadium compound, of the magnesium-containing carrier, which is obtained by reaction of an organomagnesium compound of the structure of MgPh,.nMgCl,.mR,O (n=0.37˜0.7; m≧1; R,O=ether; Ph=phenyl) with an organic chloride compound in a mole ratio of organic chloride compound/Mg≧0.5, at −20˜80° C. According to the method for producing the catalyst, it is possible to provide a catalyst which can control the distribution of molecular weight, and when polymerization is performed using this catalyst, it is possible to restrain the inactivation and to secure a sufficient activity. Moreover, the polymer produced by the use of this catalyst proves to have a high bulk density and an adjusted particle size distribution.
