Metal complexes of Group 4 replaced; catalytic compositions made with these Complex procedures; polymerization of monomers by Addition polymerizing the monomers using cyclic compounds and Precursors of the fraction of these complexes

摘要

Group 4 metal complexes of the constrained geometry type, catalysts derived therefrom and polymerization processes using the same, characterized by a nitrogen containing aliphatic or cycloaliphatic moiety that is substituted with one or more aryl groups, an aryl-substituted silane bridging group, or one or more Group 14 organometalloid substituted hydrocarbyl substituents on the metal.
