Abstract
Certain olefins such as ethylene, .alpha.-olefins and cyclopentene can be polymerized by using catalyst system containing a nickel or palladium .alpha.-diimine complex, a metal containing hydrocarbylation compound, and a selected Lewis acid, or a catalyst system containing certain nickel II! or palladium II! compounds, an .alpha.-diimine, a metal containing hydrocarbylation compound, and optionally a selected Lewis acid. The process advantageously produces polyolefins useful for molding resins, films, elastomers and other uses.
