ABSTRACT:
An intermetallic compound is disclosed. The compound is formed by reacting a first reaction product, the first reaction product being the product of reaction of a polymeric transition metal oxide alkoxide with a reducing metal having a higher oxidation potential than the transition metal, the polymeric transition metal oxide alkoxide being the product of the controlled partial hydrolysis of a transition metal alkoxide, with a first halide activator to produce a second reaction product. The second reaction product, in turn, is reacted with a second halide activator to form the intermetallic compound. The intermetallic compound is useful as a catalyst component in a catalyst system for the polymerization of alpha-olefins. The catalyst system includes, in addition to the intermetallic compound, a cocatalyst, an organic compound which includes an element selected from the group consisting of aluminum and boron.
