Patent ID: 7825200

Claim:
A process for the co-polymerization of an olefin, comprising: a. polymerizing an olefin with an initiating monomer; and b. conducting said polymerizing in the presence of a metal compound, said metal compound comprising a Group 10 transition metal complex, said complex comprising any combination of two neutral metal complexes, the combinations having one of the general formulas (I-IV): wherein: M is a Group 10 transition metal; A is π-allyl, substituted π-allyl, π-benzyl, or substituted π-benzyl; X is N or P; Y is O, CH 2 , or S; L is N or P or a structure that is capable of forming a neutral two electron donor ligand; L 1 is a neutral monodentate ligand and L 2 is a monoanionic monodentate ligand, or L 1 and L 2 taken together are a monoanionic bidentate ligand, provided that said monoanionic monodentate ligand or said monoanionic bidentate ligand is capable of adding to said olefin; B is a bridge connecting covalently an unsaturated carbon and L; is a single or double bond; R 1 , R 2 , R 3A and R 3B are the same or different and are each independently hydrogen, hydrocarbyl group, or substituted hydrocarbyl bearing functional group; R 3B is nothing when B is connected to L by a double bond.
