ABSTRACT:
A process is disclosed for improving the productivity of a polymerization catalyst formed from a magnesium ethoxide. The process comprises treating the magnesium ethoxide with a silane alkoxide at or above the temperature at which any alcohol which may be bound to the ethoxide dissociates from the alkoxide prior to subjecting the magnesium ethoxide to metathesis.
