ABSTRACT:
A catalyst composition for polymerizing alpha-olefins is prepared by treating a carrier containing OH groups with an organomagnesium composition and contacting the thus-formed magnesium-containing carrier with a solution of a titanium (IV) alkoxide and a brominating and/or chlorinating agent. The adjustment of the molar ratio of the brominating and/or chlorinating agent to the titanium alkoxide yields catalysts which produce polymers of varying molecular weight distribution, as measured by the melt flow ratio (MFR) values. Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalyst composition.
