Attenuated post-metallocene catalysts |
| abstract |
A method of making an attenuated-light-off post-metallocene catalyst ("attenuated post- metallocene catalyst" or "attenuated P-M catalyst"), the method comprising combining a faster- light-off catalyst with an effective amount of a kinetics modifier compound of formula (A1), (B1), or (C1): R5-C≡C-R6 (A1), (R5)2C=C=C(R6)2 (B1), or (R5)(R7)C=C(R6)(R7) (C1) as defined herein under effective reaction conditions to give an attenuated post-metallocene catalyst that exhibits an attenuated light-off kinetics profile (relative to that of the faster-light- off catalyst); wherein the faster-light-off catalyst has been made by activating a post- metallocene precatalyst (i.e., an unactivated "coordination entity" or "ligand-metal complex") of structural formula (I): (D)dM(T)t(Q)q(X)x (I) as defined herein; and related methods, compositions and uses. |
