ABSTRACT:
Reaction products of organic magnesium compounds and silyl esters and/or poly (silyl esters) are contacted with transition metal compounds to yield active polymerization catalysts. In a preferred embodiment, the active polymerization catalyst is further activated by contacting with a halogenating agent soluble in a hydrocarbon solvent.
