Abstract:
A process for forming a polyolefin comprising contacting at least one olefinic compound with a catalyst composition comprising a compound represented by the general formula: whereinR independently represents hydrogen atom; C1-C11 alkyl; aryl; or substituted aryl, provided that R represents at least one hydrogen atom, and z is 0 when A is oxygen or sulfur or z is 1 when A is nitrogen; R1 represents a hydrogen atom; C1-C11 alkyl; aryl; substituted aryl wherein the substitution group is selected from C1-C4 alkyl, perfluoroalkyl, nitro, sulfonate or halo group; arylalkyl; siloxyl ((â€”OSiE3) where E is selected from phenyl or C1-C4 alkyl); nitro group; sulfonate group; halo atom; or a hydrocarbyl terminated oxyhydrocarbylene group (â€”(BO)zR7) wherein each B independently is selected from a C1-C4 alkylene or an arylene group, O represents oxygen, R7 represents a C1-C11 hydrocarbyl group and z is an integer of 1 to 4); R2 represents hydrogen atom, aryl, substituted aryl, C1-C11 alkyl, halogen atom or R1 and R2, together, provide a hydrocarbylene or substituted hydrocarbylene which forms an aromatic or non-aromatic carbocyclic ring; R3 represents hydrogen; R4 represents hydrogen atom, a C1-C11 alkyl; an aryl; substituted aryl group; or R3 or R4, together, provide a hydrocarbylene or substituted hydrocarbylene forming a non-aromatic carbocyclic ring; R5 represents a C1-C11 alkyl; cycloalkyl; aryl group; a substituted aryl having one or both ortho positions of the aromatic group substituted with a C1-C4 alkyl, the para position (with respect to the Nâ€”R5 bond) substituted with a hydrogen, nitro, trifluoromethyl, halogen, methoxy, C1-C4 alkyl, sulfonate or fused or unfused aryl group; or a hydrocarbyl terminated oxyhydrocarbylene group (â€”(BO)2R7); or R1 and R5 together form an oxyhydrocarbylene chain, â€”(BO)mBâ€”, wherein each B is independently selected from a C1-C4 alkylene group or an arylene group and m is an integer of 1-4; n represents an integer of 0 or 1; R6 represents, when n is 1, an unsubstituted or substituted aromatic group; a C1-C11 alkyl; a hydrogen atom or halogen atom or when, n is 0, R6 represents an allyl group or substituted allyl group; L represents a coordination ligand selected from triphenylphosphine, tri(C1-C6 alkyl) phosphine, tricycloalkyl phosphine, diphenyl alkyl phosphine, dialkyl phenylphosphine, triphenoxyphosphine, trialkylamine, C2-C20 alkene, substituted C2-C4 alkene, C1-C4 alkoxy, pyridine, di(C1-C3 alkyl)ether, tetrahydrofuran, or a nitrile; X represents a hydrogen atom or an electron withdrawing group selected from NO2, halo, sulfonate (SO3âˆ’), sulfonyl ester (SO2R), carboxyl (COOâˆ’), a perfluoroalkyl, or a carboxylic ester group; M represents a Group VIII transition metal selected from Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt in the +2 oxidation state; and A represents oxygen, nitrogen or sulfur; in combination witha Lewis base selected from ethers, esters, aldehydes, ketones, alcohols, amides, organocarbonates, organotin compounds, water and mixtures thereof.
