• The olefin polymerization behavior of bis (phenoxy-imine) group 4 transition metal complexes (named FI Catalysts) is described. In association with methylalumoxane (MAO) or <SUP>i</SUP>Bu<SUB>3</SUB>Al/Ph<SUB>3</SUB>CB (C<SUB>6</SUB>F<SUB>5</SUB>)<SUB>4</SUB>, FI Catalysts display unique catalytic performance and have created a variety of polyolefin-based materials. For example, FI Catalysts are capable of producing vinyl-terminated low molecular weight polyethylenes (<I>M</I><SUB>v</SUB> < 2000), well-defined multimodal polyethylenes, ultra-high molecular weight amorphous ethylene-propylene copolymers (<I>M</I><SUB>w</SUB> > 10, 000, 000), highly syndiotactic polypropylenes with extremely high peak melting temperatures (<I>T</I><SUB>m</SUB> > 150°C), various block copolymers from ethylene and propylene and stereo- and regio-irregular high molecular weight poly (1-hexene)s. Many of these polymers were unavailable prior to the development of FI Catalysts. Additionally, studies on new cocatalysts for FI Catalysts have resulted in the discovery of FI Catalyst/MgCl<SUB>2</SUB>-based compound systems, which represent the first examples of MAO- and fluoroarylborate-free highly active single-site catalyst systems based on group 4 transition metal complexes.
