Abstract
The present invention is directed to processes of polymerizing olefin monomers and copolymerizing olefin monomer(s) with functionalized alpha-olefin monomers in the presence of certain late transition metal pyrrolaldimine chelates, especially bidenate or in the presence of a combination of a transition metal in its zero valence and a pyrrolaldimine represented by the formula: wherein each R1, R2, R3, R4, R5, R6, M and L are defined in the specification herein below.
