Abstract: This invention relates to a method to selectively oligomerize olefins comprising contacting olefins with: 1) at least one diaryl-substituted diphosphine ligand; 2) a chromium metal precursor; and 3) optionally, one or more activators. In a particular embodiment, the method for selectively oligomerizing olefins includes trimerizing ethylene to selectively form 1-hexene.

Abstract: This invention relates to copolymers produced by a polymerization method comprising contacting at least one olefin monomer, at least one polar monomer, an optional activator, and a catalyst compound represented by the formula: wherein M is selected from groups 3-11 of the periodic table; L1 represents a formal anionic ligand, L2 represents a formal neutral ligand, a is an integer greater than or equal to 1; b is greater than or equal to 0; c is greater than or equal to 1, E is nitrogen or phosphorus, Ar0 is arene, R1-R4 are, each independently, selected from hydrogen, hydrocarbyl, substituted hydrocarbyl or functional group, provided however that R3 and R4 do not form a naphthyl ring, N is nitrogen and O is oxygen.
