Abstract
A solution polymerization process for the preparation of homopolymers of ethylene and copolymers of ethylene and higher .alpha.-olefins and a coordination catalyst for such a process are disclosed. In the process monomer is polymerized in the presence of the coordination catalyst which consists of a particular admixture of (a) a solution of an organoaluminum compound and an organomagnesium compound, with (b) a solution of a titanium compound and a vanadium compound. The catalyst exhibits relatively high activity in the polymerization of the monomers.
