Abstract
Processes to polymerize or oligomerize olefins by contacting olefins with α-diimine metal complexes. In particular, alpha olefins can be produced in high selectivity by contacting ethylene with selected α-diimine metal complexes. In some cases an activator such as an alkylaluminum compound is also contacted with ethylene and the α-diimine metal complexes.
