Abstract
This invention is directed to novel Group 8-10 transition metal catalysts and to batch or continuous polymerizations using these catalysts. The catalysts of the present invention readily convert ethylene and &agr;-olefins to high molecular weight polymers, and allow for olefin polymerizations under various conditions, including ambient temperature and pressure, and in solution. Preferred catalysts are group 8-10 transition metals having certain dipyridyl ligands bonded thereto.
