ABSTRACT:
A catalyst is disclosed for the polymerization and co-polymerization of olefins with functionalized monomers. The catalyst is formed from a combination of two neutral metal complexes, L(iPr2)M(CH2Ph)(PMe3)[L=N-(2,6-diisopropylphenyl)-2-(2,6-diisopropylphenylimino)propanamide] and M(COD)2(COD=cyclooctadiene). The catalyst displays a unique mode of action and performs at ambient conditions producing high molecular weight polyolefins and co-polymers with functional groups. The polymerized olefins include ethylene, α-olefins and functionalized olefins.
