Abstract
Abstract A catalyst component comprising the product formed by heating at from 150*C. to 400*C., the secondary and/or tertiary alkoxide of the metals of Groups IVB, VB, and VIB, and, optionally, aluminum trialkyl, secondary aluminum alkoxide or tertiary aluminum alkoxide, the heating being done optionally in the presence of hydrocarbon solvent and/or tertiary alcohol and/or water; polymerization catalysts comprising (a) the catalyst component and (b) at least one alkyl or aryl of the metals of Groups IA, IIA, IIB, and IIIA; and a process for polymerization of ethylenically unsaturated olefins which utilizes the above polymerization catalyst.
