Attenuated post-metallocene catalysts |
| abstract |
A method of making an attenuated-light-off post-metallocene catalyst, the method comprising combining a faster-light-off catalyst with an effective amount of a kinetics modifier compound of formula (A 1 ), (B 1 ), or (C 1 ): R 5 -C≡C-R 6 (A 1 ), (R 5 )2 C =C=C(R 6 ) 2 (B 1 ), or (R 5 )(R 7 )C=C(R 6 )(R 7 ) (C 1 ) as defined herein under effective reaction conditions to give an attenuated post-metallocene catalyst that exhibits an attenuated light-off monomer uptake 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 of structural formula (I) as defined herein; and related methods, compositions and uses. |
