Abstract:
1. A process for the polymerization of an ethylenically unsaturated monomer comprising: (a) providing a transition metal catalyst component characterized by the formula: wherein R 1 and R 2 are the same or different and are each a C 1 -C 20 alkyl group, a C 4 -C 20 cycloalkyl group, or a substituted or unsubstituted aryl group having from 6-30 carbon atoms, M is a transition metal and X is an alkyl group, an aryl group, or a halogen; (b) providing an activating co-catalyst component; and (c) contacting said catalyst component and said co-catalyst component in a polymerization reaction zone with an ethylenically unsaturated monomer under polymerization conditions to produce a polymer product by the polymerization of said monomer.
