Abstract
Novel group 4 organometallic compounds, supported on anions by means of at least one covalent metal-oxygen bond, are obtained by reaction of at least one borate or aluminum comprising at least one hydroxy group with at least one group 4 transition metal compound. These compounds are used in a catalytic composition implemented in an olefin oligomerization or polymerization method.
