ABSTRACT:
This invention relates to a novel highly active and more efficient catalyst system for polymerizing alpha-olefins to prepare high, medium, and low molecular weight polymers. This highly active olefin polymerization catalyst therefore can be used to prepare both olefin waxes as well as high molecular weight crystalline polyolefins. This highly efficient, highly active catalyst is prepared by reacting a vanadium tetrahalide with a titanium tetravalent member in a hydrocarbon medium. The product of this reaction is then combined with an activating component, such as triethyl aluminum, to form a highly active and efficient polyolefin catalyst.
