摘要:
The instant invention provides a late transition metal complex which can be used with an activating cocatalyst to produce polymers and copolymers. The invention also provides methods for polymerizing olefins, as well as copolymers having polar monomers incorporated therein. More specifically, the invention provides a composition having the formula LMXZn, wherein M is selected from the group consisting of Cu, Ag and Au; X is selected from the group consisting of halide, hydride, triflate, acetate, borate, C1 through C12 alkyl, C1 through C12 alkoxy, C3 through C12 cycloalkyl, C3 through C12 cycloalkoxy, aryl, thiolate, nitrate, sulfate, nitrile, hydroxide and any other moiety into which a monomer can insert; Z is selected from the group consisting of halide, hydride, triflate, acetate, borate, C1 through C12 alkyl, C1 through C12 alkoxy, C3 through C12 cycloalkyl, C3 through C12 cycloalkoxy, aryl, thiolate, carbon monoxide, nitrate, nitrile, hydroxide, sulfate, olefins, water, any other neutral coordinating ligand and any other moiety into which a monomer can insert; n equals 0, 1 or 2; and L is a multi-dentate nitrogen-containing ligand.

A composition having the formula I where R1 and R2 are independently hydrogen, C1 to C12 linear and branched alkyl, C3 to C12 cycloalkyl, aryl, C1 to C12 alkoxy, F, Cl, SO3, C1 to C12 perfluoroalkyl, and N(CH3)2, R3 is independently selected from the group consisting of hydrogen, C1 to C12 linear and branched alkyl, C3 to C12 cycloalkyl, aryl, and 2,2,2-trifluoroethyl, A is —C(R4)—, —(CH2)x—, —(CH2)xNH(CH2)x—, or —CY2CY2—, where R4 is a hydrocarbyl, halosubstituted hydrocarbyl, or alkoxy group of from 1 to 12 carbon atoms, x is an integer from 1 to 12, and Y is halogen, and X is halogen, triflate, acetate, trifluoroacetate, hydride, or tetrafluoroborate. When combined with an activating co-catalyst is useful in polymerizing olefinic monomers.
