ABSTRACT:
A method of forming a polyolefin catalyst component includes halogenating metal complexes. The metal complexes result from reacting a metal alkoxide with an alcohol-ether. A particular non-limiting example is a magnesium complex formed by reacting magnesium alkoxide with an ethylene alcohol-ether, and then chlorinating the magnesium complex. Catalyst components, catalysts, catalyst systems, polyolefin polymers and methods of making each are disclosed.
