摘要： Embodiments of the present disclosure are directed towards bicyclic hafnium metallocenes having non-identical ligands and compositions including the bicyclic hafnium metallocenes having non-identical ligands. The bicyclic hafnium metallocene having non-identical ligands is represented by formula (I): ABMX2, where: A is a bicyclic structure; and B is a cyclopentadienyl; M is hafnium; and X is a leaving group, wherein the bicyclic structure comprises a ((C1-C6)alkyl)n-substituted Cp ring and a non-aromatic cyclic structure fused with the ((C1-C6) alkyl)n-substituted Cp ring such that the bicyclic structure includes 7 to 9 ring carbon atoms and wherein subscript n is 1, 2, or 3.

摘要： Processes of polymerizing olefin monomers. The process comprising reacting ethylene and optionally one or more olefin monomers in the presence of a catalyst system, wherein the catalyst system comprises: hydrocarbyl-modified methylaluminoxane having less than 25 mole percent trihydrocarbyl aluminum compounds AlRA1RB1RC1 based on the total moles of aluminum, where RA1, RB1, and RC1 are independently linear (C1-C40)alkyl, branched (C1-C40)alkyl, or (C6-C40)aryl; and one or more metal-ligand complexes according to formula (I):

摘要： A method of making a poly(ethylene-co-1-alkene) copolymer having a reverse comonomer distribution, the method comprising contacting ethylene and at least one 1-alkene with an effective catalyst therefor under effective gas-phase or slurry-phase polymerization conditions, thereby making the poly(ethylene-co-1-alkene) copolymer having a reverse comonomer distribution; wherein the effective catalyst is made by contacting a ligand-metal complex of formula (I), as described herein, with an activator under activating conditions.

摘要： Embodiments of the present disclosure directed towards converting a non-metallocene precatalyst into a productivity enhanced non-metallocene catalyst. As an example, the present disclosure provides a method of making an productivity enhanced non-metallocene catalyst, the method comprising combining a first non-metallocene precatalyst, an effective amount of an activator, and an effective amount of a productivity-increasing organic compound under conditions effective for the activator and the productivity-increasing organic compound to chemically convert the first non-metallocene precatalyst into the productivity enhanced non-metallocene catalyst; wherein the productivity-increasing organic compound is of formula (A), as detailed herein.

摘要： 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 (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 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.
